+2017.02.23 - GNU nano 2.7.5 "Nijntje" can properly search and replace
+		the \B and \b regex anchors, correctly repaints things
+		when multiline regexes with identical start and end are
+		involved, fixes a crash with zero-length regex matches,
+		does replacements at the edges of a marked region right,
+		no longer hides double-width characters at the head of
+		softwrapped rows, displays at most three warnings at
+		startup, and documents the ability to read a file from
+		standard input.  Come tickle my ears.
+
+2017.01.10 - GNU nano 2.7.4 "Red dress" undoes deletions in an orderly
+		manner again (bug was introduced in previous version),
+		sets the preferred x position for vertical movements
+		more consistently, avoids some scrolling problems in
+		softwrap mode, installs the Info manual also when your
+		system lacks 'makeinfo', and corrects the behavior of
+		the beginning-of-word anchor (\<) in regex searches.
+
+2016.12.28 - GNU nano 2.7.3 "Ontbijtkoek" wipes away a handful of bugs:
+		your editor is now able to handle filenames that contain
+		newlines, avoids a brief flash of color when switching
+		between buffers that are governed by different syntaxes,
+		makes the Shift+Ctrl+Arrow keys select text again on a
+		Linux console, is more resistant against malformations
+		in the positionlog file, and does not crash when ^C is
+		typed on systems where it produces the code KEY_CANCEL.
+		Oh, and it no longer mistakenly warns about editing an
+		unlocked file just after saving a new one.  That's it.
+		Tastes great with thick butter.
+
+2016.12.12 - GNU nano 2.7.2 "Shemesh! Shemesh!" brings another feature:
+		the ability to complete with one keystroke (^] by default)
+		a fragment of a word to a full word existing elsewhere in
+		the current buffer.  Besides, this release fixes two bugs
+		related to using line numbers in softwrap mode, allows to
+		use the PageUp and PageDown keys together with Shift on
+		VTE-based terminals, stops the help lines from flickering
+		during interactive replacing, makes a "set fill" override
+		an earlier "set nowrap", properly restores the selected
+		region after an external spell check, and improves a few
+		other tidbits.  If you should find any more bugs, please

   <p>The <a href="http://www.debian.org/">Debian GNU/Linux</a> distribution, known for its strict standards in distributing truly &quot;free&quot; software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but the versions available at the time were not truly free software in the <a href="http://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>
   <p><b>The event...</b></p>
   <p>It was in late 1999 when Chris Allegretta (our hero) was yet again complaining to himself about the less-than-perfect license Pico was distributed under, the 1000 makefiles that came with it and how just a few small improvements could make it the Best Editor in the World (TM). Having been a convert from Slackware to Debian, he missed having a simple binary package that included Pine and Pico, and had grown tired of downloading them himself.</p>
-  <p>Finally something snapped inside and Chris coded and hacked like a madman for many hours straight one weekend to make a (barely usable) Pico clone, at the time called TIP (Tip Isn't Pico). The program could not be invoked without a filename, could not save files, had no help text display, spell checker, and so forth. But over time it improved, and with the help of a few great coders it matured to the (hopefully) stable state it is today.</p>

   <p>In February 2001, nano was declared an official GNU program by Richard Stallman. nano also reached its first production release on March 22, 2001.</p></blockquote>
 <h2><a name="1.5"></a>1.5. Why the name change from TIP?</h2>
 <blockquote><p>On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program &quot;establishes a full duplex terminal connection to a remote host&quot;, and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).</p></blockquote>

Then you must create an Environment variable called HOME which points to the directory where you put nano.rc.  In Windows XP, you can get to Environment variables by right-clicking "My Computer" either on the desktop or in the Start Menu, and selecting Properties.  This should bring up the System Properties panel.  Then click the Advanced Tab, and there should be a button called Environment Variables.  Click that to bring up the Environment Variables section. Now, under User Variables you should be able to click the New button, and make a new Variables Name called HOME, with the Variable Value of whatever path you copied nano.rc into (just the directory name; don't add nano.rc onto the end).</p>

-<blockquote><p>It was decided that consistency was nice, but people are used to Pico's inconsistent behavior. Also, in version 1.1.99pre1, search and replace history was introduced. If you wish to edit your previous search/replace entry (or any previous entry), you can do so by hitting the up arrow to cycle through your history. This method allows the best of both worlds: You don't need to erase the previous string if you want to enter a new one, but you can with one keystroke recall previous entries for editing. Therefore there is now no "Pico mode", nano is and has always been a Pico <b>clone</b>, and clones by default should be compatible.</p></blockquote>

-.SH NOM
-nano \- NAno un NOuvel éditeur, un clone libre et amélioré de Pico
-
-.SH SYNOPSIS
-.B nano
-.I [OPTIONS]\ [[+LIGNE,COLONNE]\ FICHIER]...
-.br
-
-.SH DESCRIPTION
-Cette page de manuel décrit brièvement la commande \fBnano\fR.
-.PP
-.\" TeX users may be more comfortable with the \fB<whatever>\fP and
-.\" \fI<whatever>\fP escape sequences to invoke bold face and italics,
-.\" respectively.
-\fBnano\fR est un éditeur petit, sympathique et libre, qui vise à remplacer
-Pico, l'éditeur par défaut du logiciel non libre Pine. \fBnano\fR ne se
-contentant pas de copier l'interface et l'ergonomie de Pico, il offre
-également certaines fonctions manquantes (ou désactivées par défaut)
-dans Pico. Ces fonctionnalités sont, par exemple, les fonctions de
-recherche et de remplacement, et la possibilité de sauter directement à 
-une ligne et à une colonne précise.
-
-.SH OPTIONS
-.TP
-.B +\fILIGNE\fP,\fICOLONNE\fP
-Démarre avec le curseur positionné à la colonne \fICOLONNE\fP de 
-la ligne \fILIGNE\fR (l'un des deux, au moins, devant être spécifié) au 
-lieu de démarrer à la colonne\ 1, ligne\ 1.
-.TP
-.B \-?
-Identique à \fB\-h (\-\-help)\fP.
-.TP
-.B \-A (\-\-smarthome)
-Rend plus malin le fonctionnement de la touche «\ Début\ ». Lorsque l'on
-appuie sur cette touche à n'importe quel endroit excepté au tout début
-du texte d'une ligne (i.\ e. au premier caractère non blanc), le curseur
-se positionnera au début du texte de la ligne (qu'il soit en avant ou en
-arrière). Si le curseur est déjà là, il se placera au vrai début de la
-ligne.
-.TP
-.B \-B (\-\-backup)
-Lors de l'écriture d'un fichier, crée une copie de sécurité de la
-version précédente, en ajoutant un tilde (~) au nom du fichier.
-.TP
-.B \-D (\-\-boldtext)
-Utilise des caractères gras à la place de la vidéo inverse.
-.TP
-.B \-C \fIrépertoire\fP (\-\-backupdir=\fIrépertoire\fP)
-Définit le répertoire utilisé par \fBnano\fP pour enregistrer les copies 
-de sécurité uniques si celles-ci sont activées.
-.TP
-.B \-E (\-\-tabstospaces)
-Convertit les tabulations clavier en espaces.
-.TP
-.B \-F (\-\-multibuffer)
-Active le mode multi-espace, autorisant l'édition simultanée de 
-plusieurs fichiers, si ce mode est disponible.
-.TP
-.B \-H (\-\-historylog)
-Enregistre les chaînes ayant fait l'objet d'une recherche ou d'un
-remplacement dans le fichier \fI~/.nano_history\fR afin de permettre leur
-réutilisation. Ceci n'est possible que si \fBnano\fR est configuré pour
-utiliser les fichiers nanorc.
-.TP
-.B \-I (\-\-ignorercfiles)
-Ne pas utiliser pas les fichiers \fISYSCONFDIR/nanorc\fR et 
-\fI~/.nanorc\fR (si \fBnano\fR est capable de les utiliser).
-.TP
-.B \-K (\-\-rebindkeypad)
-Interprète les touches du pavé numérique afin qu'elles fonctionnent 
-toutes correctement. Vous ne devriez utiliser cette option que si ce 
-n'est pas le cas, car nano ne sera plus capable d'utiliser la souris 
-correctement lorsque cette option sera activée.
-.TP
-.B \-L (\-\-nonewlines)
-Ne pas ajouter de passage à la ligne à la fin des fichiers.
-.TP
-.B \-N (\-\-noconvert)
-Désactive la conversion automatique des fichiers depuis les formats Mac et
-DOS.
-.TP
-.B \-O (\-\-morespace)
-Utiliser la ligne blanche située sous la ligne de titre comme
-espace supplémentaire d'édition.
-.TP
-.B \-Q \fIchaîne\fP (\-\-quotestr=\fIchaîne\fP)
-Définit le préfixe par défaut des citations. Nano utilise ce préfixe
-pour réaliser une justification correcte des citations. Si nano est
-capable d'utiliser des expressions rationnelles, le préfixe par défaut
-sera "\fI^([\ \\t]*[#:>\\|}])+\fP", sinon, ce sera "\fI>\ \fP". Dans 
-l'expression rationnelle précédente, «\ \fI\\t\fP\ » représente une 
-tabulation.
-.TP
-.B \-R (\-\-restricted)
-Mode restreint\ : aucune lecture ou écriture de fichiers non indiqués 
-sur la ligne de commande, pas de lecture des fichiers nanorc, 
-interdiction de suspendre, interdiction d'ajouter au début, à la fin, 
-de sauvegarder un fichier ayant déjà un nom sous un nom différent, 
-d'utiliser une copie de sécurité ou le correcteur orthographique. Cette 
-option peut aussi être activée en appelant \fBnano\fP sous un nom 
-commençant par «\ r\ » (par exemple «\ rnano\ »).
-.TP
-.B \-S (\-\-smooth)
-Active le défilement progressif. Le texte défilera ligne-par-ligne au lieu
-de défiler morceau-par-morceau.
-.TP
-.B \-T \fInombre\fP (\-\-tabsize=\fInombre\fP)
-Définit la taille (largeur) des tabulations en nombre de colonnes. Le 
-nombre indiqué doit être strictement supérieur à 0. La valeur par défaut 
-est de 8.
-.TP
-.B \-U (\-\-quickblank)
-Effacement rapide de la ligne d'état. Les messages affichés par la ligne 
-d'état disparaîtront après une frappe clavier au lieu de 25. Notez que
-l'option \fB-c\fP prend le pas sur cette option.
-.TP
-.B \-V (\-\-version)
-Affiche la version, puis s'arrête.
-.TP
-.B \-W (\-\-wordbounds)
-Détection plus précise des limites de mots, obtenue en considérant les

-.SH "FICHIERS D'INITIALISATION"
-\fBnano\fR lit les fichiers d'initialisation dans l'ordre suivant\ : 
-\fISYSCONFDIR/nanorc\fR, puis \fI~/.nanorc\fR. Référez-vous à la page de 
-manuel de \fBnanorc(5)\fR et au fichier d'exemple \fInanorc.sample\fR, 
-qui devraient tous les deux être livrés avec \fBnano\fR.
-
-.SH NOTES
-Si aucun correcteur orthographique de remplacement n'est indiqué dans la 
-ligne de commande ou dans l'un des fichiers nanorc, \fBnano\fR prendra 
-la commande indiquée par la variable d'environnement \fBSPELL\fR si 
-elle est définie.
-
-Dans certains cas, \fBnano\fR essaiera de sauvegarder le fichier en cours
-d'édition dans un fichier de secours. Cela arrivera principalement si
-\fBnano\fR reçoit un signal SIGHUP ou SIGTERM, ou bien se trouve à court de
-mémoire. Le nom de ce fichier de secours sera \fInano.save\fR si le fichier en
-cours n'avait pas encore de nom, ou sera composé du nom du fichier en cours
-suivi du suffixe «\ .save\ ». Si un fichier de ce nom existe déjà dans
-le répertoire, un «\ .save\ » et un nombre seront ajoutés à la fin du
-nom du fichier en cours afin de le rendre unique (par exemple,
-«\ .save.1\ »). En mode multi-espace, \fBnano\fR réalisera une
-sauvegarde de tous les fichiers en cours dans leurs fichiers de secours
-respectifs.

-.SH NOM
-nanorc \- fichier de configuration de l'éditeur nano du projet GNU 
-
-.SH DESCRIPTION
-Cette page de manuel décrit brièvement le fichier de configuration de 
-l'éditeur \fBnano\fP GNU.
-.PP
-\fBnano\fP est un petit éditeur sympathique et libre, qui vise à 
-remplacer Pico, l'éditeur par défaut du logiciel non libre Pine. 
-\fBnano\fP ne se contentant pas de copier l'interface et l'ergonomie de 
-Pico, il offre également certaines fonctionnalités manquantes (ou 
-désactivées par défaut) de Pico. Ces fonctionnalités sont, par exemple, 
-les fonctions de recherche et de remplacement et la possibilité de 
-sauter directement à une ligne et à une colonne précise.
-.PP
-Le fichier \fInanorc\fP contient les paramètres par défaut de 
-\fBnano\fP. Il ne doit pas être au format DOS ou Mac. Lors de son 
-démarrage, nano commencera par lire le fichier de configuration général 
-\fISYSCONFDIR/nanorc\fP, puis lira le fichier de configuration personnel 
-de l'utilisateur \fI~/.nanorc\fP.
-
-.SH OPTIONS
-Le fichier de configuration accepte une série de commandes \fBset\fP 
-(activer) et \fBunset\fP (désactiver), qui permettent de définir le 
-paramétrage de nano au démarrage sans avoir à utiliser d'options de
-ligne de commande. De plus, les mots clefs \fBsyntax\fP (syntaxe),
-\fBcolor\fP (couleur) et \fBicolor\fP (couleur insensible à la casse) 
-sont utilisés pour définir les règles de colorisation pour différents 
-motifs de texte. \fBnano\fP lit une commande par ligne.
-
-Les options du fichier de configuration ont priorité sur les valeurs par 
-défaut utilisées par nano. Les options de la ligne de commande sont 
-prioritaires par rapport aux options du fichier de configuration. Les 
-options sont désactivées (unset) par défaut, sauf les options prenant un 
-argument.
-
-Les apostrophes («\ \fI'\fP\ ») et les guillemets droits («\ \fI"\fP\ »)
-présents dans des chaînes de caractères utilisées comme paramètres n'ont 
-pas besoin d'être précédées d'une barre oblique inversée
-(«\ \fI\\\fP\ »). La chaîne sera terminée par le dernier guillemet 
-droit. Par exemple, pour l'option \fBbrackets\fP, "\fI"')>]}\fP" 
-correspondra à \fI"\fP, \fI'\fP, \fI)\fP, \fI>\fP, \fI]\fP et \fI}\fP.
-
-Les commandes et arguments reconnus sont\ :
-
-.TP 3
-.B set/unset autoindent
-Active l'indentation automatique.
-.TP
-.B set/unset backup
-Crée des copies de sécurité nommées
-.IR nom_du_fichier~ .
-.TP
-.B set backupdir "\fIrépertoire\fP"
-Définit le répertoire utilisé par \fBnano\fP pour enregistrer les copies 
-de sécurité uniques, si l'enregistrement de copies de sécurité est 
-activé.
-.TP
-.B set/unset backwards
-Par défaut, les recherches se font vers l'arrière.
-.TP
-.B set/unset boldtext
-Utilise des caractères gras à la place de la vidéo inverse.
-.TP
-.B set brackets "\fIchaîne\fP"
-Définit les caractères considérés comme des crochets fermants lors de la 
-justification des paragraphes. Ces caractères ne doivent pas contenir 
-d'espaces. Seules les ponctuations terminales, éventuellement suivies 
-de crochets fermants, peuvent terminer une phrase.
-
-La valeur par défaut de cette option est\ : "\fI"')>]}\fP".
-
-N.D.T.\ : reportez-vous au paragraphe sur l'option \fBpunct\fR pour 
-plus d'informations.
-
-.TP
-.B set/unset casesensitive
-Par défaut, les recherches ne tiennent pas compte de la casse.
-.TP
-.B set/unset const
-Affiche en permanence la position du curseur dans la ligne d'état.
-.TP
-.B set/unset cut
-Par défaut, coupe le texte du curseur à la fin de la ligne, au lieu de 
-couper la ligne entière.
-.TP
-.B set fill \fIn\fP
-Passe automatiquement à la ligne une fois arrivé à la colonne 
-\fIn\fR. Si la valeur indiquée est de 0 ou moins, le point de passage à 
-la ligne aura lieu à la taille de l'écran moins \fIn\fR. Cela permet de 
-faire varier le point de passage à la ligne lorsque l'on change la 
-taille de l'écran. La valeur par défaut est de \-8.
-.TP
-.B set/unset historylog
-Active l'utilisation de
-.I ~/.nano_history
-pour enregistrer et relire les chaînes ayant fait l'objet d'une 
-recherche ou d'un remplacement.
-.TP
-.B set matchbrackets "\fIchaîne\fP"
-Définit les crochets ouvrants et fermant pour la recherche de crochets 
-correspondants. Cette liste ne doit pas contenir de blancs. L'ensemble 
-des crochets ouvrants doit être indiqué en premier, suivi de l'ensemble 
-des crochets fermant, qui doit être dans le même ordre. La valeur par 
-défaut de cette option est "\fI(<[{)>]}\fP".
-.TP
-.B set/unset morespace
-Utiliser la ligne blanche située sous la ligne de titre comme espace 
-supplémentaire d'édition.
-.TP
-.B set/unset mouse
-Active l'utilisation de la souris, si elle est disponible pour votre
-système. Lorsque celle-ci est activée, il est possible d'utiliser la
-souris pour positionner le curseur, pour marquer le texte (avec un
-double-clic) et pour lancer les fonctions correspondant aux raccourcis.
-Il est possible d'utiliser la souris sous X\ Window ou en mode console
-avec gpm.
-.TP
-.B set/unset multibuffer
-Mode multi-espace\ : permet de charger les fichiers dans leur propre 
-espace.
-.TP
-.B set/unset noconvert
-Pas de conversion depuis les formats DOS et Mac.
-.TP
-.B set/unset nofollow
-Ne suit pas les liens symboliques lors de l'écriture des fichiers.
-.TP
-.B set/unset nohelp
-Désactive les lignes d'aide affichée en bas de l'écran.
-.TP
-.B set/unset nonewlines
-Ne pas ajouter de passage à la ligne à la fin des fichiers.
-.TP
-.B set/unset nowrap
-Désactive le passage automatique à la ligne.
-.TP
-.B set operatingdir "\fIrépertoire\fP"
-\fBnano\fP ne lira et n'écrira des fichiers qu'à l'intérieur du 
-\fIrépertoire\fP et de ses sous-répertoires. De plus, celui-ci devient 
-le répertoire courant, afin que les fichiers soient lus depuis ce 
-répertoire. Par défaut, cette fonction est désactivée.
-.TP
-.B set/unset preserve
-Préserve les séquences XON et XOFF (^Q et ^S).
-.TP
-.B set punct "\fIchaîne\fP"
-Définit les caractères interprétés comme des ponctuations terminales 
-lors de la justification des paragraphes. Ces caractères ne peuvent 
-inclure de blancs. Seules les ponctuations terminales, éventuellement 
-suivies de crochets fermants, peuvent terminer une phrase. La valeur par 
-défaut de cette option est "\fI!.?\fP".
-
-N.D.T.\ : ce réglage permet, lors de la justification, de conserver
-2\ espaces au lieu d'une derrière les ponctuations terminales, ce qui 
-correspond aux normes typographiques anglo-saxonnes, mais n'a pas lieu 
-d'être en français. Pour le français, le plus simple est d'indiquer, 
-dans le fichier nanorc, une chaîne vide pour ce paramètre.
-.TP
-.B set/unset quickblank
-Effacement rapide de la ligne d'état. Les messages affichés par la ligne
-d'état disparaîtront après une frappe clavier au lieu de 25.
-.TP
-.B set quotestr "\fIchaîne\fP"
-Définit le préfixe par défaut utilisé pour les citations dans les 
-courriers électroniques. Ce préfixe est utilisé pour réaliser une 
-justification correcte de ces citations. Il s'agira, si votre système le 
-permet, d'une expression rationnelle étendue. Dans le cas 
-contraire, il s'agira d'une chaîne de texte brut. Si vous disposez des 
-expressions rationnelles, la valeur par défaut de cette option sera 
-"\fI^([\ \\t]*[#:>\\|}])+\fP", sinon, ce sera ">\ ". Notez que le
-«\ \\t\ » ci-dessus correspond à un caractère de tabulation.
-.TP
-.B set/unset rebinddelete
-Interprète différemment la touche «\ Supprimer\ », afin que les touches 
-«\ Effacement arrière\ » et «\ Supprimer\ » fonctionnent correctement. 
-Vous ne devriez avoir besoin de cette option que si, sur votre système, 
-la touche «\ Effacement arrière\ » produit l'effet de la touche «\ 
-Supprimer\ ».
-.TP
-.B set/unset rebindkeypad
-Interprète les touches du pavé numérique afin qu'elles fonctionnent 
-toutes correctement. Vous ne devriez utiliser cette option que si ce 
-n'est pas le cas, car nano ne sera plus capable d'utiliser la souris 
-correctement lorsque cette option sera activée.
-.TP
-.B set/unset regexp
-Utilise par défaut des expressions rationnelles étendues pour les 
-recherches.
-.TP
-.B set/unset smarthome
-Rend plus malin le fonctionnement de la touche «\ Début\ ». Lorsque
-cette touche est pressée à n'importe quel endroit excepté au tout début
-du texte d'une ligne (i.\ e. au premier caractère non blanc), le curseur
-se positionnera au début du texte de la ligne (qu'il soit en avant ou en 
-arrière). Si le curseur est déjà là, il se placera au vrai début de la 
-ligne.
-.TP
-.B set/unset smooth
-Active le défilement ligne-par-ligne du texte.
-.TP
-.B set speller "\fIprogramme\fP"
-Utilise le correcteur orthographique \fIprogramme\fP au lieu du 
-correcteur intégré, qui s'appuie sur \fIspell\fP.
-.TP
-.B set/unset suspend
-Autorise à suspendre \fBnano\fP.
-.TP
-.B set tabsize \fIn\fP
-Utilise une taille de tabulation de \fIn\fP colonnes. Cette valeur doit 
-être strictement supérieure à 0. La valeur par défaut est de\ 8.
-.TP
-.B set/unset tabstospaces
-Convertit les tabulations clavier en espaces.
-.TP
-.B set/unset tempfile
-S'il a été modifié, le fichier sera sauvegardé automatiquement en 
-quittant, sans demande de confirmation.
-.TP
-.B set/unset view
-Interdit de modifier les fichiers.
-.TP
-.B set whitespace "\fIchaîne\fP"
-Définit les deux caractères utilisés pour afficher les premiers 
-caractères des tabulations et des espaces. Ces deux caractères doivent 
-être mono-colonne.
-.TP
-.B set/unset wordbounds
-Détection plus précise des limites de mots, obtenue en considérant les
-caractères de ponctuation comme faisant partie des mots.
-.TP
-.B syntax "\fIchaîne\fP" ["\fImotif_de_fichier\fP" ... ]
-Définit une syntaxe nommée \fIchaîne\fP qui pourra être activé via 
-l'option \fB-Y\fP (ou \fB--syntax\fP) ou qui sera automatiquement 
-activée si le nom du fichier en cours correspond à l'expression 
-rationnelle étendue \fImotif_de_fichier\fP. Toutes les instructions 
-suivantes de colorisation \fBcolor\fP ou \fBicolor\fP s'appliqueront à 
-cette syntaxe, jusqu'à la définition d'une nouvelle syntaxe.
-
-La syntaxe nommée \fInone\fP (aucune) est réservée\ ; si elle est 
-indiquée dans la ligne de commande, cela revient à ne définir aucune 
-syntaxe. La syntaxe nommée \fIdefault\fP (par défaut) est spéciale, elle 
-ne nécessite aucun motif de \fImotif_de_fichier\fP, et s'applique aux 
-fichiers ne correspondant à aucun des \fImotif_de_fichier\fP des autres 
-syntaxes.
-.TP
-.B color \fIcouleur_texte\fP[,\fIcouleur_fond\fP] "\fImotif\fP" ...
-Pour la syntaxe en cours, affiche toutes les expressions correspondant à 
-l'expression rationnelle étendue \fImotif\fP en utilisant la couleur de 
-texte \fIcouleur_texte\fP et la couleur de fond \fIcouleur_fond\fP, 
-l'une de ces deux couleurs au moins devant être définie. Les couleurs 
-acceptées par \fBnano\fP pour le texte et le fond sont\ : \fIwhite\fP 
-(blanc), \fIblack\fP (noir), \fIred\fP (rouge), \fIblue\fP (bleu), 
-\fIgreen\fP (vert), \fIyellow\fP (jaune), \fImagenta\fP, et \fIcyan\fP. 
-Pour la couleur du texte, vous pouvez ajouter à ces couleurs le préfixe 
-\fIbright\fP (lumineux) pour obtenir une couleur plus lumineuse. Si 
-votre terminal est capable de gérer la transparence, ne pas spécifier de 
-\fIcouleur_fond\fP indique à \fBnano\fP d'essayer d'utiliser un fond 
-transparent.
-.TP
-.B icolor \fIcouleur_texte\fP[,\fIcouleur_fond\fP] "\fImotif\fP" ...
-Comme ci-dessus, mais la recherche des motifs est effectuée sans tenir 
-compte de la casse.
-.TP
-.B color \fIcouleur_texte\fP[,\fIcouleur_fond\fP] start="\fImotif_début\fP" end="\fImotif_fin\fP"
-Affiche les expressions commençant par l'expression rationnelle étendue 
-\fImotif_début\fP et se terminant par l'expression rationnelle étendue 
-\fImotif_fin\fP en utilisant la couleur de texte \fIcouleur_texte\fP 
-et la couleur de fond \fIcouleur_fond\fP, l'une de ces deux couleurs au 
-moins devant être définie. Cela permet à la colorisation syntaxique de 
-s'étendre sur plusieurs lignes. Notez que toutes les occurrences 
-successives de \fImotif_début\fP après le \fImotif_début\fP initial 
-seront surlignées jusqu'à la prochaine instance de \fImotif_fin\fP.
-.TP
-.B icolor \fIcouleur_texte\fP[,\fIcouleur_fond\fP] start="\fImotif_début\fP" end="\fImotif_fin\fP"
-Comme ci-dessus, mais la recherche des motifs est effectuée sans tenir 
-compte de la casse.
-.TP
-.B include "\fIfichier_de_syntaxes\fP"
-Lit le fichier \fIfichier_de_syntaxes\fP contenant une liste 
-autosuffisante de définitions de syntaxes. Ce fichier ne doit contenir 
-que des commandes \fBsyntax\fP, \fBcolor\fP et \fBicolor\fP.

-\fBnano\fR est un éditeur petit, sympathique et libre, qui vise à 
-remplacer Pico, l'éditeur par défaut du logiciel non libre Pine. 
-\fBnano\fR ne se contentant pas de copier l'interface et l'ergonomie de 
-Pico, il offre également certaines fonctions manquantes (ou désactivées 
-par défaut) dans Pico. Ces fonctionnalités sont, par exemple, les 
-fonctions de recherche et de remplacement, et la possibilité de sauter 
-directement à une ligne et à une colonne précise..
-.PP
-\fBrnano\fP est une version de \fBnano\fP fonctionnant en mode 
-restreint, qui ne permet d'éditer que les fichiers indiqués et qui 
-n'autorise pas l'utilisateur à accéder au système de fichier ou à un 
-interpréteur de commandes.
