-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]
