+# This file is meant to be sourced by updmap and enhance the --enable and
+# --disable options with the functionality needed to deal with Debian's
+# generated updmap.cfg.
+
+# This is the planned scheme how it works
+# 
+# A for disableMap:
+#   1. create a list of files to act on (either in sysconfdir only, or in user dirs too)
+#   2. grep for not-commented lines in these files that contain $map
+#   3. for each of these files, run configReplace appropriately
+#
+# B for enableMap:
+#   1. create a list of files to act on (either in sysconfdir only, or in user dirs too)
+#   2. grep for commented lines in these files that contain $map
+#   2.1. if any are found, check whether it is only one
+#   2.1.1 if there is only one, run configReplace on that file appropriately
+#   2.1.2 if there is more than one, the precedence is 
+#         XX*local*.cfg > 10tetex-base.cfg > 20tetex-extra.cfg > any
+#   2.1.2.1 if it's clear on which file to act, run configReplace on that file
+#           appropriately
+#   2.1.2.2 if unclear (i.e. only "any"), exit with an error
+#   2.2 if none are found, act on 99local.cfg (could be made configurable)
+#       - if 99local.cfg does not exist, create it (with an explanatory comment)
+#       - run configReplace on it appropriately
+#
+# After that, update-updmap must be run (in the appropriate mode!), and then updmap
+# must reexecute itself.  Since disableMap is called by enableMap, we need a wrapper
+# for it.  An alternative would be to do this just before the creation of the output
+# files, but I think it's easier this way, and currently updmap only enables one Map
+# file per run.
