Usage: maelstrom_addon_package.pl zipfile [pkgname]
|
|
|
|
Creates a Slackware tgz package from a Maelstrom addon zip file. The
|
|
zipfile may be either a local file (e.g. "my_addon.zip") or a URL
|
|
(e.g. "http://example.com/foo_addon.zip").
|
|
|
|
The output file will be located in /tmp, and will be named
|
|
|
|
maelstrom_addon_pkgname-YYYYMMDD-noarch-1_mael.tgz
|
|
|
|
where pkgname is the [pkgname] argument, or derived from the zipfile name if
|
|
no [pkgname] is given on the command line, and YYYYMMDD is the current date.
|
|
|
|
The resulting .tgz package is suitable for installation with installpkg.
|
|
However, only one Maelstrom addon package may be installed at a time
|
|
(since the addon filenames are the same, the 2nd one would overwrite the
|
|
first one).
|
|
|
|
Since the script must be able to create files as the root user, you
|
|
must run it with root privileges (e.g. with su or sudo).
|
|
|
|
You can find a collection of Maelstrom add-on zip files here:
