15# An ebuild sets this to `yes' if an automatic installation and/or upgrade is
16# not possible. The ebuild should overwrite pkg_postinst() and explain the
17# reason for this BEFORE calling webapp_pkg_postinst().

20# @DESCRIPTION:
21# An ebuild sets this to `yes' to make webapp support optional, in which case
22# you also need to take care of USE-flags and dependencies.
