This is a TERRIBLE article. Saxophobia ( talk) 17:34, 25 January 2015 (UTC) reply

This article could use a lot more work from interested topic experts. The two most pressing concerns: 1) historical information is lacking and not presented in an accessible chronological way (a separate "History" section would be useful, if enough information can be found). 2) WP:NOTGUIDE information is far too detailed and should be trimmed down to the most significant facts about the various processes.
