ABC standard Vim scripts Copyright 2012 Lee Savide <email@example.com> This product includes software developed for the Vim text editor, and for the ABC music notation standard. Portions of this software were based on code from the ABNF description of the ABC standard, written by Henrik Norbeck, found at http://www.norbeck.nu/abc/bnf/abc20bnf.htm, or as a text file at http://www.norbeck.nu/abc/bnf/abc20bnf.txt . This software contains code derived from the ABC standard, version 2.1. The standard is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported license. Please read the license terms at http://creativecommons.org/licenses/by-nc-sa/3.0/, and if you wish to, read the full license deed at http://creativecommons.org/licenses/by-nc-sa/3.0/legalcode . Additionally, the ABC standard now uses keywords that conform to RFC 2119, and as such, the standard conforms to the following: The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119. In addition to the key words above, the key word "VOLATILE" is used to indicate sections which are under active discussion and/or likely to change in some future version of the standard. Any comments used in the source code of the Vim scripts included in this software also conform to the key words as described above, and in RFC 2119.
