Copy files from the source directory to component directories
in the destination directory as specified by the package file.
Options:
--source <source directory>
Specifies the directory from which to copy the files
specified in the file passed via --file. Can also be
abbreviated to: --src, --s.
Required.
--destination <destination directory>
Specifies the directory in which to create the component
directories and copy the files specified in the file passed
via --file. Can also be abbreviated to: --dest, --d.
Required.
--file <package file>
Specifies the file listing the components to be created in
the destination directory and the files to copy from the
source directory to each component directory in the
destination directory. Can also be abbreviated to: --f.
Required.
--os [dos|mac|unix]
Specifies which type of system this is. Used for parsing file
specifications from the package file. Can also be abbreviated
to: --o.
Required.
--help
Prints this information. Can also be abbreviated to: --h
Optional.
--debug [1-10]
Controls verbosity of debugging output, 10 being most verbose.
1 : same as --verbose.
2 : includes function calls.
3 : includes source and destination for each copy.
Optional.
--verbose
Print component names and files copied/deleted. Can also
be abbreviated to: --v.
Optional.
e.g.
$0 --os unix --source /builds/mozilla/dist --destination /h/lithium/install --file packages-win --os unix --verbose
Note: options can be specified by either a leading '--' or '-'.
