+# Original Author: Jim Ramsay <lack@gentoo.org>
+#
+# Purpose:
+#   Provides common methods used by (almost) all gkrellm plugins:
+#    - Sets up default dependencies
+#    - Adds pkg_setup check to ensure gkrellm was built with USE="X" (bug
+#    167227)
+#    - Provides 'gkrellm-plugin_dir' function in lieu of hard-coding the plugins
+#    directory (which *may* change in the future)
+#    - Provides the most common src_install method to avoid code duplication.
+#
+# Utility Routines:
+#   gkrellm-plugin_dir - Returns the gkrellm-2 plugin directory
+#
+# Environment:
+#   For pkg_setup:
+#     PLUGIN_NO_XCHECK - If set, the default check ensuring that gkrellm2 is
+#       built with USE="X" is skipped, allowing plugins to build with the
+#       gkrellmd-only case.  Defaults to unset.
+#   For src_install:
+#     PLUGIN_SO - The name of the plugin's .so file which will be installed in
+#       the plugin dir.  Defaults to "${PN}.so".
+#     PLUGIN_DOCS - An optional list of docs to be installed.  Defaults to
+#       unset.
+#
+# Changelog:
+#   09 March 2007: Jim Ramsay <lack@gentoo.org>
+#     - Initial commit
