Editing RBBS-PC (section)

==License==
RBBS-PC was not in [[public domain]], but copyrighted and released under a limited license. The license allowed free distribution of both [[source code]] and binary in non-modified form. The documentation from an early 1984 CPC12.1 release lists the following conditions:<ref>[http://software.bbsdocumentary.com/IBM/DOS/RBBS/rbbs121.txt RBBS-PC Version CPC12.1 Documentation]</ref>
* RBBS-PC CPC12 is not distributed in modified form,
* No fee or other consideration is charged, and
* Reference to the authors is retained.

In the final 17.4 release from 1992 the license conditions were almost identical:<ref name="rbbs17.4">[http://software.bbsdocumentary.com/IBM/DOS/RBBS/rbbs-doc.zip RBBS-PC, r17.4 package. This file contains the RBBS-PC documentation, required to understand the operation of RBBS-PC.]</ref>
* You may NOT distribute RBBS-PC in modified form.
* You may NOT charge a fee for RBBS-PC itself, and
* You MUST retain all references to the copyright and authors.

While the modified form distribution was not allowed, the documentation encouraged to publish and share modifications (bug fixes, new features) as [[Patch (computing)|patch files]] against the original source code. RBBS-PC had its own .MRG file format and tool for patching.
