# This eclass is no longer useful. Most of it has been superseded by
|
||||
# new EAPI features such as REQUIRED_USE and USE dependencies.
|
||||
# The remaining functions are very specialized (probably to PHP)
|
||||
# and were not used for a long time. The last consumer is now redundant
|
||||
# to a new stable version and will be removed soon.
|
||||
# The eclass will be removed in 30 days.
