+# setting a repo specific umask
+# ----------------------------------------------------------------------
+# this is for people who are too paranoid to trust e.g., gitweb's repo
+# exclusion logic, but not paranoid enough to put it on a different server
+
+=for usage
+
+ * In the rc file, add the line
+ 'RepoUmask',
+ somewhere in the ENABLE list
+
+ * For each repo that is to get a different umask than the default, add a
+ line like this:
+
+ option umask = 0027
+
+ * Anytime you add or change the value, if there are existing repos that
+ would be affected, you will need to do a manual "chmod" adjustment,
+ because umask only affects newly created files.
