-# @FUNCTION: prune_libtool_files
-# @USAGE: [--all|--modules]
-# @DESCRIPTION:
-# Locate unnecessary libtool files (.la) and libtool static archives
-# (.a) and remove them from installation image.
-#
-# By default, .la files are removed whenever the static linkage can
-# either be performed using pkg-config or doesn't introduce additional
-# flags.
-#
-# If '--modules' argument is passed, .la files for modules (plugins) are
-# removed as well. This is usually useful when the package installs
-# plugins and the plugin loader does not use .la files.
-#
-# If '--all' argument is passed, all .la files are removed without
-# performing any heuristic on them. You shouldn't ever use that,
-# and instead report a bug in the algorithm instead.
-#
-# The .a files are only removed whenever corresponding .la files state
-# that they should not be linked to, i.e. whenever these files
-# correspond to plugins.
-#
-# Note: if your package installs both static libraries and .pc files
-# which use variable substitution for -l flags, you need to add
-# pkg-config to your DEPEND.
