Subject: Initial OHM grammar for extends tag
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=72ab9b5015d54b3cf23e4b7e08580c756fefed22;p=thirdparty%2Fjinja.git

Initial OHM grammar for extends tag

OHM is a PEG-based grammar parser generator which seems to be more
compatible with the Jinja language. We are not making use of their
automatic space handling since in Jinja whitespace is significant.
