970N/A# Undo libtool damage to makefiles to allow us to control the linker
98N/A# settings that libtool tries to force on us.
1276N/A#
98N/A# Usage: delibtoolize.pl [-P] <path>
911N/A# -P - Use large pic flags (-KPIC/-fPIC) instead of default/small (-Kpic/-fpic)
1276N/A# -s - Only track libraries from a single file at a time, instead of across all
1276N/A# files in a project
