-# Short Desc:  Creates symlink to the latest version of multiple slotted
-#              packages.
-#
-# Long Desc:
-#
-#  When a package is SLOT'ed, very often we need to have a symlink to the
-#  latest version. However, depending on the order the user has merged them,
-#  more often than not, the symlink maybe clobbered by the older versions.
-#
-#  This eclass provides a convenience function that needs to be given a
-#  list of alternatives (descending order of recent-ness) and the symlink.
-#  It will choose the latest version it can find installed and create
-#  the desired symlink.
-#
-#  There are two ways to use this eclass. First is by declaring two variables
-#  $SOURCE and $ALTERNATIVES where $SOURCE is the symlink to be created and
-#  $ALTERNATIVES is a list of alternatives. Second way is the use the function
-#  alternatives_makesym() like the example below.
-#
-# Example:
-#
-#  pkg_postinst() {
-#      alternatives_makesym "/usr/bin/python" "/usr/bin/python2.3" "/usr/bin/python2.2"
-#  }
-#
-#  The above example will create a symlink at /usr/bin/python to either
-#  /usr/bin/python2.3 or /usr/bin/python2.2. It will choose python2.3 over
-#  python2.2 if both exist.
-#
-#  Alternatively, you can use this function:
-#
-#  pkg_postinst() {
-#     alternatives_auto_makesym "/usr/bin/python" "/usr/bin/python[0-9].[0-9]"
-#  }
-#
-#  This will use bash pathname expansion to fill a list of alternatives it can
-#  link to. It is probably more robust against version upgrades. You should
-#  consider using this unless you are want to do something special.
