Revision 1086 - Directory Listing
Modified Mon Jun 9 20:40:00 2003 UTC (9 years, 11 months ago) by gage 
Added a variable to set the environment variable
use by HTML_img.  This is too close to one used by HTML_dpng but we can use it for now:

	$envir{'externalLatexPath'}   		=	$Global::externalLaTeX2HTMLPath;

	$envir{'externalLaTeXPath'}   		=	$Global::externalLatexPath;  #used by HTML_img
(note capitalizations of T's FIXME

Revision 880 - Directory Listing
Modified Thu May 22 16:19:49 2003 UTC (10 years ago) by apizer 
rename course access_log to answer_log so that it will not be confused with the system access log.
Revision 856 - Directory Listing
Modified Fri May 16 23:30:46 2003 UTC (10 years ago) by jj 
Added global variable for default delimiters/vertical lines in display_matrix.
Revision 767 - Directory Listing
Modified Sun Mar 2 21:07:24 2003 UTC (10 years, 2 months ago) by gage 
Added the preprocessing facility.

The current default preprocessor is a filter which takes the initial PG problem
and handles the BEGIN_TEXT/END_TEXT blocks as well as escaping backslashes and
replacing ~~ by backslash.

Other preprocessors can be installed to effect different behavior.

At present there is only one preprocessor.  The behavior of the method
preprocess could be modified to allow a chain of preprocessing filters
if that becomes desirable.

The barest bones of a postprocessing facility is also in place.  The
current default postprocessor does nothing.  This could be implemented
to create sticky answers.
Revision 762 - Directory Listing

Modified Fri Feb 28 16:32:13 2003 UTC (10 years, 2 months ago) by gage

replaced \&main::PG_floating_point_exception_handler by
