qepcad 1.69 Fri, 16 Mar 2012 Added -h and -noecho command-line options. Use of # as a comment character. Note that at present, some Qepcad sub-commands, like those for plotting, probably don't allow for the comment character. This will require some more investigation than I have time for right now. Cleaned up code for processing command line arguments in Qepcad. Right now it should report errors on unkown options, and it doesn't process options processed by saclib. Updated cad2d's MAIN.c so that it's in line with some recent improvements to Qepcad. qepcad 1.62 Tue, 10 May 2011 A bug in introduced in version 3.82 of GNU make causes the call to make in $qe/source to fail. I filed a bug report (bug report #33274) but, since that may never be fixed or at any rate folks will be using 3.82 for a while, I modified $qe/source/Makefile to work around the problem. The makefile is harder to mantain now, but at least it works. qepcad 1.59 Thu, 17 Mar 2011 Cleaned and reorganized code dealing with intialization and cleanup. As part of that, Qepcad now redefines Saclib's FAIL function so that child Singular processes are cleaned up before exiting. qepcad 1.56 Wed, 02 Mar 2011 Fixed bug that caused segfault when plotting partial CADs. Fixed bug-esque problem in plot2d that maxed out the CPU purposely ... GLUT's idle callback was happening about 1,000,000 times a second! qepcad 1.55 Tue, 08 Jun 2010 Fixed some issues with rendering. In particular, ADJ2D_plot no longer relies on FIFOs, it is now simple pipes. qepcad 1.54 Thu, 15 Apr 2010 Modified code to compile properly for 64-bit architectures. This relies on having at least saclib2.2.3 and tests the __WORDSIZE macro to see whether its value is 32 or 64.
