[Wikitex-l] Gnuplot questions

Well  said,  John;  another  solution  would  be  to  update
Apache's $PATH.  I'll add something to that effect.

WikiTeX restricts local I/O out-of-the-box;  but  if  you're
running  in  a  protected environment, consider relaxing the
quote   restriction    in    wikitex.php    on    line    82
($arrBlack['plot']).  Then it's a matter of negotiating with
the web server; but absolute paths should do the trick.

Great idea; let's get complete error dumps with, say, a con-
figurable threshold.

Would you mind scripting up a quick reproduction?

     As  far as the color irregularities: gnuplot depends on
libpng, I believe; see if you can't determine which  version
SF is running.

     P.S.   Line  46  in  wikitex.sh  under wt_anch() should
read:

STR=$(printf '<a href="%s">%s</a>' "${OUT}${HASH}" "${STR}")

which accounts for the problems viewing the source, and will
make its way into the latest branch.
