+# @DESCRIPTION:
+# The webapp eclass contains functions to handle web applications with
+# webapp-config. Part of the implementation of GLEP #11
+
+# @ECLASS-VARIABLE: WEBAPP_DEPEND
+# @DESCRIPTION:
+# An ebuild should use WEBAPP_DEPEND if a custom DEPEND needs to be built, most
+# notably in combination with WEBAPP_OPTIONAL.

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