# \brief Tool for assembling a package archive

define HELP_MESSAGE
Compress and sign depot content for publishing
usage:
2018-02-26 16:05:34 +00:00
$(firstword $(MAKEFILE_LIST)) <archive-path> {PUBLIC_DIR=<public>}
The <archive-path> denotes the archives (and implicitly their
dependencies) to publish from the depot to the public directory.
It must be given including the version number of the package archive.
This tool does not touch any Genode source repository. It solely
reads from the depot and writes to the public directory.
2018-02-26 16:05:34 +00:00
The optional 'PUBLIC_DIR' argument defines the location of the public
directory. If not specified, '<genode-dir>/public/' is used.
