FreeDOS 1.3 will include Free software and open source software where possible.

See also FreeDOS 1.3 Packages

Note that some licenses are very old and pre-date the popularity of the GNU GPL (v1 in 1989, v2 in 1991) or the Open Source Initiative (1998). Other programs use their own licenses or other licenses not recognized or evaluated by GNU or OSI. These licenses will need to be evaluated. Goal will be to include programs with licenses that are suitably "free" and "open source."
