===== dCore sce-ppa-add Command =====

The ''sce-ppa-add'' command is only present in Ubuntu-based dCores. It is used to add PPAs ([[https://help.launchpad.net/Packaging/PPA|Personal Package Archives]]) to an Ubuntu-based dCore system. This allows the user to add additional software from outside Ubuntu's already huge repositories!

The ''sce-ppa-add'' command turns a PPA argument into an apt source by prepending "[[http://ppa.launchpad.net/|https://ppa.launchpad.net]]" and adding dCore's distro and version, specified in /usr/share/doc/tc/*, plus an optional second argument that is interpreted as a repository (defaults to "main"). The ''sce-ppa-add'' command shares the basic format of the Ubuntu command.

More information regarding PPAs and sources can be found in the [[http://forum.tinycorelinux.net/index.php/board,75.0.html|dCore Extra Repositories]] sub-forum. The [[http://wiki.tinycorelinux.net/dcore:handling_extensions#additional_repositories|dCore Extra Repositories]] wiki section provides some additional information. Ubuntu's [[https://launchpad.net/ubuntu/+ppas|PPA search page]] may also be useful. As per the Ubuntu warning outlined below, exercise caution when installing software from external sources.

Usage options from the 'sce-ppa-add –help' command:

  sce-ppa-add - Add a PPA (Personal Package Archive) entry in /opt/debextra.
                For use with Ubuntu-based dCore ports.
  
  Ubuntu warning: PPAs do not undergo the same validation process as packages in
  the main Ubuntu repositories. PPA keys are cryptographically signed but are
  still a lower security alternative to the main repository. The user will
  be installing software at their own risk.
  
  Usage:
  
  sce-ppa-add PPA_NAME Create a PPA entry in /opt/debextra/. Use exact PPA_NAME
                       provided by the PPA (eg. sce-ppa-add ppa:midori/ppa).
                       Re-run command for each PPA added. Manually remove PPA
                       entry from /opt/debextra/ as desired. Use sce-import to
                       install the actual extension and create an SCE.
