1 " tcsh.vim: Vim syntax file for tcsh scripts
2 " Maintainer: Gautam Iyer <gi1242@users.sourceforge.net>
3 " Modified: Sat 16 Jun 2007 04:52:12 PM PDT
5 " Description: We break up each statement into a "command" and an "end" part.
6 " All groups are either a "command" or part of the "end" of a statement (ie
7 " everything after the "command"). This is because blindly highlighting tcsh
8 " statements as keywords caused way too many false positives. Eg:
12 " causes history to come up as a keyword, which we want to avoid.
14 " Quit when a syntax file was already loaded
