# update_mozilla_launcher_symlinks
# --------------------------------
# Create or remove the following symlinks in /usr/bin:
#
#    firefox -> firefox-bin
#    thunderbird -> thunderbird-bin
#    mozilla -> mozilla-bin
#    sunbird -> sunbird-bin
#
# The symlinks are removed if they're found to be dangling.  They are
# created according to the following rules:
#
# - If there's a -bin symlink in /usr/bin, and no corresponding
#   non-bin symlink, then create one.
#
# - Can't do this in src_install otherwise it overwrites the one
#   for the non-bin package.
#
# - Link to the -bin symlink so it's easier to detect when to
#   remove the symlink.
#
# NOTE: This eclass does *not* manage the launcher stubs in /usr/bin except
# when a -bin package is installed and the corresponding from-source
# package is not installed.  The usual stubs are actually installed in
# src_install so they are included in the package inventory.
