1" Vim syntax file for the "papp" file format (_p_erl _app_lication)
2"
3" Language:	papp
4" Maintainer:	Marc Lehmann <pcg@goof.com>
5" Last Change:	2009 Nov 11
6" Filenames:    *.papp *.pxml *.pxsl
7" URL:		http://papp.plan9.de/

9" You can set the "papp_include_html" variable so that html will be
10" rendered as such inside phtml sections (in case you actually put html
11" there - papp does not require that). Also, rendering html tends to keep
12" the clutter high on the screen - mixing three languages is difficult
13" enough(!). PS: it is also slow.
14
15" pod is, btw, allowed everywhere, which is actually wrong :(
