#
# 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
