OK, I will do it ASAP.

There is already a lib directory, but holds font and map files. We could=20
take the opportunity to change this, as the files in that directory all=20
have cvs version 1.1, and no cvs history will be lost.
They could be moved to a new directory called "data", after all they are=20
installed in $(prefix)/...../data/.
Only in the main Makefile.am a data subdirectory needs to be added in=20
src_dirs to accomplish this.
Does everybody agrees with this?

The default plplot configuration will be with-double, as everybody=20
agreed on this (even if by omission).
If the user specified that he wants floats instead, he must have its own=20
reasons, and must have what he wants (and deserves).
Don't you agree?

If it's OK for you is fine for me :)
