qb64/LICENSE/COPYING.TXT

=== IMPORTANT LICENSING NOTE FOR QB64 PROGRAMMERS ===
All executables created with QB64 are subject to the LGPL licence conditions.
All executables which read sound files are subject to the GPL license as well (due to incorporation of libsamplerate).
When distributing your program as an executable all license requirements can be met by:
i) Making your program's source code (.BAS) available and declaring it to be GPL as well as
ii) Including this entire license folder distributed with QB64
It should be noted that the above is not the sole method one could use to abide by the license conditions
and that creating closed source QB64 programs is possible when LGPL (not GPL) code is dynamically
linked to, not embedded within your executable.
