* Changes in MMM Mode 0.5.9

Made the tests work in batch mode.

Switched from Automake to plain Makefile.

Now requires at least GNU Emacs 25.1.

Info documentation can be generated by the GNU ELPA packager.

New here document class for shell.  The new class handles indented
here documents, which are incompatible with the mmm classes shared
with Perl.

* Changes in MMM Mode 0.5.8
Support for Emacs 27.

Fixes for nesting submodes.

* Changes in MMM Mode 0.5.7
Fixes for mmm-indent-line-narrowed.

* Changes in MMM Mode 0.5.6
Emacs 25 compatibility fix when cl is not loaded.

* Changes in MMM Mode 0.5.5

Introduced mode transition hooks, like mmm-x-enter-hook and mmm-y-exit-hook.

New function mmm-indent-line-narrowed, to use as mmm-indent-line-function.

`cl-lib' is a new dependency, replacing `cl'. It comes bundled with
recent versions of Emacs, and for older ones it can be installed from
GNU ELPA.


* Changes in MMM Mode 0.5.4

Fixes for indentation, SMIE support, and minor bugs.


* Changes in MMM Mode 0.5.2

Introduced `mmm-after-syntax-propertize-functions'. A primary major
mode can set it to adjust `syntax-table' text properties in submode
regions.

New file `mmm-defaults.el'. A user can simply require it and have
basic setup for ERB, EJS and PHP files (for the last one, `php-mode'
has to be installed separately).

`mmm-add-classes' is autoloaded.

`mmm-beginning-of-syntax' was removed.

Assorted highlighting and syntax detection improvements.


* Changes in MMM Mode 0.5.1

Some minor documentation updates and bugfixes.


* Changes in MMM Mode 0.5.0

** Compatibility with recent Emacsen

Updated to work with Emacs 23 and 24. Removed some compatibility code
for older versions. Added new local variables used in the latest js-mode
and cc-engine modes.

** New submode classes

New submode classes for ERB and EJS templates, both in mmm-erb.el. It
also includes a smart indentation algorithm, supporting them together
with script and style tag subregions in HTML code.

** Parsing when idle

Setting `mmm-parse-when-idle' will make MMM Mode re-parse modified
buffers when Emacs is idle. This can lead to visible pauses, though,
depending on the size of the buffer and the number of subregions.

** Support submode-specific syntax functions

Relevant for Emacs 24: we define a composite syntax-propertize-function
that delegates syntax recognition to respective submode functions.

For users, this means regular expressions in js-mode and string
interpolations and percent literals in ruby-mode.

** Indentation

More consistent indentation behavior, the default implementation
delegates to the submode at the end of the indentation.

The major mode can provide its own implementation by setting
mmm-indent-line-function, to handle specific mode combinations better.


* Changes in MMM Mode 0.4.8

** Delimiter Regions

The delimiters which mark off submode regions now have their own
overlays.  They can be highlighted if you so desire using appropriate
class arguments and/or the variable mmm-delimiter-face.  They are also
in an appropriate major mode, or non-mode as the case may be.

** Nested Submodes

Nested submodes are now vaguely supported.

** RPM Spec File

An RPM spec file, contributed by <bishop@platypus.bc.ca>, is now
included for people who wish to build their own SRPM to install from.

** New Submode Classes

Many thanks to Joe Kelsey for writing a very intelligent class for
editing Noweb files, and to Alan Shutko for one for CWeb files.  We
also have a mode for SGML DTD definitions from Yann Dirson.

** Numerous bugfixes and small improvements


* Changes in MMM Mode 0.4.7

** Multiple Decoration Levels

You now have finer control over how colorful your submode regions are,
via `mmm-submode-decoration-level'.  Level 0 turns coloring off--no
