A minor buglet in 1.1.13, all .tex files were missing (removed)
from the ./docs subdirectory, causing the build to fail:
make
cd parser ; make pyplucker;
make[1]: Entering directory `/tmp/plucker-1.1.13/parser'
cd python ; make
make[2]: Entering directory `/tmp/plucker-1.1.13/parser/python'
all done
make[2]: Leaving directory `/tmp/plucker-1.1.13/parser/python'
make[1]: Leaving directory `/tmp/plucker-1.1.13/parser'
make[1]: Entering directory `/tmp/plucker-1.1.13/docs'
make[1]: *** No rule to make target `Plucker_Doc.tex', needed by
