Sphinx: List of supported languages for highlighting?

pygmentize -L lexers lists all supported lexers.

• http://pygments.org/languages/
• http://pygments.org/docs/lexers/
• http://pygments.org/docs/cmdline/#getting-help

As far as I can tell, the list is in the file pygments/lexers/_mapping.py, in the (autogenerated) dictionary LEXERS. In my copy, I see a line

'ObjectiveCLexer': ('pygments.lexers.compiled', 'Objective-C', ('objective-c', 'objectivec', 'obj-c', 'objc'), ('*.m',), ('text/x-objective-c',)),

I think this should mean that any of the tags objective-c, objectivec, obj-c, or objc should work, as long as your version of Pygments is up-to-date. They work for me.
