 <blockquote><p>Funny you should ask!</p>
  <p><b>In the beginning...</b></p>
  <p>For years Pine was THE program used to read email on a Unix system. The Pico text editor is the portion of the program one would use to compose his or her mail messages. Many beginners to Unix flocked to Pico and Pine because of their well organized, easy to use interfaces. With the proliferation of GNU/Linux in the mid to late 90's, many University students became intimately familiar with the strengths (and weaknesses) of Pine and Pico.</p>
@@ -80,30 +88,30 @@
  <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 in 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>

+<h3><a name="1.3"></a>1.3. Why the name change from TIP?</h3>
 <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>

 <blockquote><p>If you're using the official nano .zip file and have extracted all the files, you should take the file nano.rc and place it somewhere on your Win32 system (for example, if you have write permission to do so, at the top of C:\).  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>
  <p>We're still working on documentation for enabling syntax highlighting on Win32; please bear with us.</p>
  <p>Note that the nano.rc file must remain Unix-formatted in order for nano to understand it.  In other words, you should probably use only nano to edit its config file.  Other programs like Wordpad and Notepad will convert the file to DOS format when saving, and the latter does not even properly read Unix-formatted files to begin with.</p></blockquote>
