VERSION = "1.0.2"
VERSION_TEXT = "mtime_cache v#{VERSION}"
USAGE = <<ENDUSAGE
Usage:
mtime_cache [<globs>] [-g globfile] [-d] [-q|V] [-c cache]
ENDUSAGE
HELP = <<ENDHELP
Traverse through globbed files, making a json cache based on their mtime.
If a cache exists, changes the mtime of existing unchanged (based on MD5
hash) files to the one in the cache.
Options:
globs Ruby-compatible glob strings (ex some/path/**/*.java)
A extension pattern is allowd in the form %{pattern}
(ex some/path/*.{%{pattern1},%{pattern2}})
The globs support the following patterns:
%{cpp} - common C++ extensions
-g, --globfile A file with list of globs to perform (one per line)
-?, -h, --help Show this help message.
-v, --version Show the version number (#{VERSION})
-q, --quiet Don't log anything to stdout
-V, --verbose Show extra logging
-d, --dryrun Don't change any files on the filesystem
-c, --cache Specify the cache file for input and output.
[Default is .mtime_cache.json]
