+# Originally written by Thomas Esser, 1998. Public domain.
+#
+# As of TeX Live 2008, the final fmtutil.cnf is generated by
+# tlmgr generate fmtutil.  You can use
+# tlmgr generate fmtutil -localcfg /some/file to make local additions.
+# See tlmgr --help for more info.
+#
+# The format of the table is:
+#
+# format  engine  pattern-file  arguments
+#
+# The last "argument" must be the name of the file on which to run
+# the ini-engine (such as initex).  If the ini-engine is e-TeX, and the
+# e-TeX extensions should be enabled, the filename must be prefixed with
+# a * character.
+# 
+# fmtutil always passes the -ini option to the engine.
+# If no pattern-file is desired, use -.
+# Either spaces or tabs can be used as separators.
+# 
+# Other notes:
+# 1) tex and amstex just load hyphen.tex. No customization.
+#    You can have your own customized (via babel's hyphen.cfg)
+#    formats on top of plain by using "bplain.tex" instead of
+#    plain.tex (see e.g. bplain.ini file for bplain format).
+#
+# 2) etex-based formats load language.def, not language.dat.
+#
+# 3) The symbolic link to the right engines (e.g. bplain -> tex)
+#    is generated by the "texlinks" script.
+# 
+# 4) usual comments start with "# ", whereas disabled configurations
+#    start with "#! " in this file.

+# 
+# The updmap.cfg in this tree (TEXMFDIST) is generated by tlmgr by
+# concatenating updmap-hdr.cfg with all updmap.cfg files found.
+#
+# To make local customizations to the map files, using one of the
+# following methods is simplest:
+#
+# 1) run
+#       updmap-sys --enable Map=foo.map
+#    for each map file.  (Or MixedMap instead of Map, if your font has
+#    both Metafont and outline definitions.)  See the updmap --help
+#    documentation. This will add lines to the updmap.cfg file in
+#    TEXMFSYSCONFIG (creating it if necessary).
+#
+# 2) put all your additional fonts into TEXMFLOCAL, edit
+#    TEXMFLOCAL/web2c/updmap.cfg, and run updmap-sys.
+#
+# See the output of updmap --help and/or
+# http://tug.org/fonts/fontinstall.html for more.
+# 
+# In any case, manual edits to TL's updmap.cfg files, psfonts.map,
+# pdftex.map, etc., will be lost on update.  So don't do that.
+#
+# The default settings of the updmap options (not maps) are specified in
+# TEXMFMAIN/web2c/updmap.cfg and can be overridden by an updmap.cfg in
+# any other tree.
