# Usage: sofix FLAGS DIR FOO.la...
#
# Change directory to DIR and do various things based on FOO.la
# vars and FLAGS, a comma-separated list of symbols:
#
#  no-symlinks -- from the files in library_names=LIST, delete
#                 those that are symlinks, and update FOO.la
#                 vars `dlname' and `library_names' as well
#
#  no-la       -- delete FOO.la
#
#  ln-s-lib    -- symlink (or copy if no-la) FOO.la to libFOO.la
#                 [default: remove any such symlinks found]
#
# To specify no flags, use "none".  Note, however, that "none"
# does not prevent any libFOO.la files from being deleted anyway.
#
# Lastly, chmod -x the remaining regular (non-symlink) files.
