To whom it may concern: on AIX, HP-UX, SunOS 5.x and Linux there is a new version of "gd" available (9506) and older versions have been renamed ( gd old = 9501, gd = 9503, gd new = 9506 ). Bugfixes: - in Landscape mode sufficient upper margin. New: - The output file extension ".eps" is treated the same way as ".ps". - Parameters binsize(), xbin(), ybin() are allowed in GPRESET and dataset. - Dataset/file name is written to the picture margin, use NODSN to suppress it. - Input files with the ".Z" extension are assumed to be created by the UNIX commands "compress" and are decompressed on the fly, thus saving your disk space. This feature is somewhat experimental and doesn't work yet under Linux. - External user fit functions can be compiled and linked with private include directories and libraries, e.g.: gdfct usrfct -I../myinc -L../mydir -lmylib Internals: - Character representation changed from ellipses to Bezier curves (-> smaller PS files) Thus characters may look slightly different (e.g. the "0") Archives - of the gd-package (the program, tutorial, HTML docs, README) for outside use are available on AIX under /d/bio/kraemer/GD/GD.* as tar'ed and compressed files for a couple of popular UNIXes (AIX, HPUX, Sun, Linux, ... ). good luck, mk
