Hi All,

Over the last few months I have worked on a package that I think may be
a good candidate for inclusion into Emacs. It has recently reached what
I consider a sufficient quality for consideration - though I anticipate
that should this be seen as promising there will likely be suggested
improvements.

This has been motivated by a desire to produce a better method of
formatting Org source blocks in PDF export, and inspired by htmlize.

Unlike htmlize, Engrave Faces provides general functionality to
transform a buffer into another format with font-lock information.
This core functionality is currently made us of in
engrave-faces-latex.el, engrave-faces-ansi.el, and engrave-faces-html.el
to provide exporters for LaTeX, ASCII/ANSI, and HTML.

Compared to htmlize and htmlfontify.el, Engrave Faces currently lacks
the ability to treat links specially, or properly handle the text
transformation performed by overlays*. However, this is also much smaller
and hopefully more maintainable.
- engrave-faces.el is 250 sloc
- engrave-faces-latex.el is 100 sloc
- engrave-faces-ansi.el is 140 sloc
- engrave-faces-html.el is 115 sloc
( *there may be other differences, but this is what's apparent to me. )

For comparison, htmlize.el is 1700 sloc and htmlfontify.el is 2200 sloc.

Engrave Faces also possesses the unique capability that it can be given
a list of preset face styles which will override the current attributes
of those faces. These overrides are also passed down with inheritance,
via an internal expansion and merging of face attribute information.
This allows one to save the details for a certain theme, and "engrave"
the buffer with font-lock attributes from that theme regardless of what
the current theme is. For ease of applying this to with your current
theme a function `engrave-faces-generate-preset' is provided which
re-generates the saved face information using the current theme.

I feel that this is likely generally useful functionality, and so would
like to offer it to Emacs to make it more accessible and more visible
for improvement.

I am currently an FSF-assigned contributor to Org mode, and assume that
this should make contributing to Emacs fairly straightforward.

Attached you may find the engrave-faces{,-latex,-ansi,-html}.el as well
as LaTeX, ASCII/ANSI, and HTML versions of engrave-faces.el for sampling.
The code is also available at https://github.com/tecosaur/engrave-faces.

All the best,
