This is the graftool distribution. It contains the necessaru
C, header, Make and other files, and the necessary directory
structure. The preferred target location is $HOME/work/src/graftool .

The following tar archives are included (to be unpacked from
within the graftool directory):

lheaders.tar: contains the full "local" include directory that
should go in $HOME/work/include.

ux11_xtb.tar: contains a subset of the xgraph distribution, with
the files that are also used in the graftool libraries. This
archive must be unpacked if xgraph is not in the expected
place to make the xtb* and ux11 links point to something.
