Thanks, Alan, for your work. I will follow the track you lead. Perhaps=20
tomorrow, or in the week-end.

Regarding the examples directory problem: from other packages that use=20
AT, a plain make installs thinks under the distribution tree, with=20
libraries in .libs directories and executables that are linked with the=20
libraries in the .libs dirs, but the real executables becomes hidden=20
(in .libs? no, under .something) and in place of the executable (i.e.=20
with the same name), is put a script that works as a wrapper to the=20
real (hidden) executabl (e.g., seting up a LD_LIBRARY_PATH that founds=20
libs in the .libs dirs).

I'm sure you know all this, but I think that this setup will be fine for=20
us, and avoids the need to install the all package after changing a=20
single line in a source file, in order to run an example.

| release except cheer you guys on to sort out the remaining rough
| spots for PLplot.
|
| Currently, those rough spots consist of the -dev tk problem and the
| above octave problems. Also, we need lots of testing of this new
