+# This script can be used to implement syntax highlighting in the cgit
+# tree-view by refering to this file with the source-filter or repo.source-
+# filter options in cgitrc.
+#
+# Note: the highlight command (http://www.andre-simon.de/) uses css for syntax
+# highlighting, so you'll probably want something like the following included
+# in your css file (generated by highlight 2.4.8 and adapted for cgit):

+# table.blob .num  { color:#2928ff; }
+# table.blob .esc  { color:#ff00ff; }
+# table.blob .str  { color:#ff0000; }

+# table.blob .slc  { color:#838183; font-style:italic; }
+# table.blob .com  { color:#838183; font-style:italic; }
+# table.blob .dir  { color:#008200; }
+# table.blob .sym  { color:#000000; }
