ANN: SCSS project development release 0.3.1

[Julian Graham]

Hi Schemers,

I am pleased to announce that the SCSS project has released version
0.3.1, our seventh development release.

SCSS is a Scheme module for parsing, querying, and emitting style
information compatible with the W3C Cascading Stylesheets
recommendation. While SCSS does not itself provide any rendering
functionality, it can provide style information to applications and
libraries that do. If used with XML documents produced by SXML or
SDOM, SCSS can accomodate the full range of selector types described
in the W3C recommendation; it can also match simple selectors against
strings when structured document information is not available.

The 0.3.1 development release is focused primarily on code
reorganization and cleanup: Via Guile's 1.8.x's support for several
new SRFIs, the SCSS codebase is a good deal more compatible with other
Scheme platforms; the lexical analyzer has been rewritten by hand,
making it an order of magnitude smaller and somewhat faster than the
previous programmatically-generated one.  Additionally, the parts of
the selection algorithm has been redesigned, allowing the system to
provide automatic and efficient management of the style cache when
dealing with changes to the set of active pseudo-elements.  See the
NEWS and TODO files included in the distribution for more detailed
information on the changes in this release.

The release can be obtained from the SCSS home page
(http://www.nongnu.org/scss/) or from the SCSS project page on
