This is a port of Libxslt 1.1.35 to MSDOS/DJGPP.


Libxslt is the XSLT C library developed for the GNOME project. XSLT
itself is a an XML language to define transformation for XML.
Libxslt is based on libxml2. It also implements most of the EXSLT set
of processor-portable extensions functions and some of Saxon's
evaluate and expressions extensions.



DJGPP specific changes.
=======================

- There are no user visible changes. Only small changes have been
done to get the test suite running due to DOS style EOL issues.

- To configure, compile and use this library, a working port of
libxml2 must be installed. The latest port is available from
ftp.delorie.com and mirrors as:
ftp://ftp.delorie.com/pub/djgpp/current/v2tk/xml2914b.zip
This means that all ports on which xml2914b.zip depends must also be
installed in the DJGPP installation used.

- The documentation is only available as a large set of html documents
and their file names are not 8.3 clean. You will need LFN support
to install them, although I do not know if html formated
documentation makes any sense on plain DOS.

- The port has been configured and compiled on WinXP SP3, Win98SE and
MS-DOS 7.10 with DOSLFN 0.41c. There is no guarantee that this may
be possible with any other DOS-like OS. Due to the use of long file
names it will not be possible to configure and compile without LFN
support. The port has been compiled using gcc346 and bnu2351b.

As usual, all djgpp specific files (diffs, README files, etc.) are
stored in the "djgpp" directory. The sources have been configured to
be build in the "0build" directory. If for some reason it does not
work for you, delete it contents and configure from scratch again.

Please read the docs to become familiar with this product.


Here is an extract of the NEWS file showing the user visible changes
