$0
Traverse component directory specified and merge multiple existing
.xpt files into single new .xpt files for improved startup time.
Options:
-s, --source <directory>
Specifies the directory from which the component files were
copied. Typically, this will be the same directory used by
pkgcp.pl.
Required.
-d, --destination <directory>
Specifies the directory in which the component directories are
located. Typically, this will be the same directory used by
pkgcp.pl.
Required.
-o, --os [dos|unix]
Specifies which type of system this is. Used for setting path
delimiters correctly.
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 --os unix --verbose
Note: options can be specified by either a leading '--' or '-'.
