# git-cache-meta -- simple file meta data caching and applying.
# Simpler than etckeeper, metastore, setgitperms, etc.
# from http://www.kerneltrap.org/mailarchive/git/2009/1/9/4654694
# modified by n1k
#  - save all files metadata not only from other users
#  - save numeric uid and gid

# Changes by: Andrey Arapov <andrey.arapov@nixaid.com>
#   2015-10-16 - add '-h' flag to chown, chgrp and touch so that symlink is
#                NOT followed
#              - chmod cannot be applied to symlink
#              - add "--" to stop processing arguments (e.g when file name has
#                leading "-")
#   2015-10-14 - added quotes around path %p

# Initial release by andris9
#   2012-03-05 - added filetime, andris9
