33 Distribution of the source code
34 ===============================
36 Most of the software distributed with Tails is taken directly from
37 upstream Debian packages, and is not modified or recompiled by
38 Tails. Software that is modified or recompiled by Tails are available
39 on [[our git repositories|/contribute/git]]. If you require or desire
40 the sources for unmodified Debian upstream packages, retrieving them
41 from Debian is the simplest solution to all parties (packages that can
42 not be found in the regular Debian archive anymore can be found at
43 <http://snapshot.debian.org/>).
45 According to the GPL licence (section 3(b) of the GPLv2 and section
46 6(b) of the GPLv3), complete sources for all Tails releases are
47 available for anyone who requests them, in DVD format, via postal
48 mail, for a nominal charge. If you only require one or two source
49 packages, Tails can work with you to send a copy of individual
50 packages electronically.
