[XeTeX] XeTeX 0.9999.0 released

[George N. White III]

In case anyone else is using Fedora 18, which provides a TeX
Live 2013/dev "preview":

$ xetex --version
XeTeX 3.1415926-2.5-0.9999 (TeX Live 2013/dev)
kpathsea version 6.1.1dev

named COPYING and the XeTeX source.
Primary author of XeTeX: Jonathan Kew.
Compiled with ICU version 49.1.1; using 49.1.1
Compiled with zlib version 1.2.7; using 1.2.7
Compiled with FreeType2 version 2.4.10; using 2.4.10
Compiled with Graphite2 version 1.1.1; using 1.1.1
Compiled with HarfBuzz version 0.9.12; using 0.9.12
Compiled with fontconfig version 2.10.2; using 2.10.2
Compiled with libpng version 1.5.13; using 1.5.13
Compiled with poppler version 0.20.2

Following the instructions for using the git repository:

 git clone git://git.code.sf.net/p/xetex/code xetex-code

gives a source tree with a build.sh script.

On Fedora 18, this build script needs to edited to use Fedora's
kpathsea library by adding the following to the list of configure
options:

 -prefix=/usr -with-system-kpathsea

This gives a working xetex:
