XO-Get is a very simple package-installer for the olpc xo-laptop.
- The repository syncs with this page: http://wiki.laptop.org/go/Xo-get/Repository
- Infos stored in a local sqlite3 db (in ~/.xo_get/main.db)
- Supported commands:
xo-get.py update xo-get.py list [categories/category_name] xo-get.py search tag/activity_name xo-get.py install activity_name
