#
# 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 utility routines in lieu of hard-coding the plugin directories.
#    - Provides the most common src_install method to avoid code duplication.
#
# Utility Routines:
#   gkrellm-plugin_dir - Returns the gkrellm-2 plugin directory
#   gkrellm-plugin_server_dir - Returns the gkrellm-2 server plugin directory
#
# Environment:
#   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.
#     PLUGIN_SERVER_SO - The name of the plugin's server plugin .so portion.
#       Defaults to unset.
#       Important: This will also cause the pkg_setup check to be skipped, so
#       you need to check 'build_with_use app-admin/gkrellm X' in your
#       src_compile and only compile the GUI portion if that returns true.  (see
#       x11-plugins/gkrelltop as an example)
#
# Changelog:
#   12 March 2007: Jim Ramsay <lack@gentoo.org>
#     - Added server plugin support
#   09 March 2007: Jim Ramsay <lack@gentoo.org>
#     - Initial commit
#
