Copy files from the source directory to component directories
in the destination directory as specified by the package file.
Options:
-s, --source <source directory>
Specifies the directory from which to copy the files
specified in the file passed via --file.
Required.
-d, --destination <destination directory>
Specifies the directory in which to create the component
directories and copy the files specified in the file passed
via --file.
Required.
NOTE: Source and destination directories must be absolute paths.
Relative paths will NOT work. Also, the destination directory
must NOT be a subdirectory of the source directory.
-f, --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.
Required.
-o, --os [dos|mac|unix]
Specifies which type of system this is. Used for parsing
file specifications from the package file.
Required.
-h, --help
Prints this information.
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.
-v, --verbose
Print component names and files copied/deleted.
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 '-'.
