After building clisp as described below, run the TL
  Build --enable-xindy CLISP=$clisp_builddir/clisp
to include xindy in the build.  It is disabled by default.

xindy/xindy-src/README-clisp has alternative instructions with some
extra information, especially for those building xindy on its own. The
process here is written for building clisp-for-xindy-for-TL. The
differences are minimal.

clisp_basedir=`pwd`

clisp_builddir=$clisp_basedir/clisp-build

There may be clisp test failures relating to sockets on some
systems. Since xindy doesn't use sockets, we can ignore those for TL.
