sbosubmit is a tool to facilitate uploading of SlackBuilds to SlackBuilds.org.
It does it by performing checks of the files to be submitted, packaging them and then uploading the resulting tarball to the SlackBuilds.org server for later approval.
For example, submitting libreoffice SlackBuild is as easy as:
$ cd /path/to/slackbuilds/office/libreoffice
$ sbosubmit
Please consult the sbosubmit(1) man page for more information.
Happy Slacking!
