13# @ECLASS-VARIABLE: WEBAPP_DEPEND

15# An ebuild should use WEBAPP_DEPEND if a custom DEPEND needs to be built, most
16# notably in combination with WEBAPP_OPTIONAL.

19# @ECLASS-VARIABLE: WEBAPP_NO_AUTO_INSTALL
20# @DESCRIPTION:
21# An ebuild sets this to `yes' if an automatic installation and/or upgrade is
22# not possible. The ebuild should overwrite pkg_postinst() and explain the
23# reason for this BEFORE calling webapp_pkg_postinst().
24
25# @ECLASS-VARIABLE: WEBAPP_OPTIONAL
26# @DESCRIPTION:
27# An ebuild sets this to `yes' to make webapp support optional, in which case
28# you also need to take care of USE-flags and dependencies.
