v0.1 (24 Feb 2003)
------------------

Bug fix:

Mistakenly assumed that all data were greater or equal to one.  Thanks
to Liz Dolan for noticing something wrong when she was profiling a
hypothetical solver with times less than one.

Change:

A non-positive value is now treated as a failure. (Is there is a
situation where a zero value could be interpreted otherwise?)

v0.2 (10 Mar 2003)
------------------

Change:

Terminal type is now an option (postscript eps is still the default).
So now "--term=X11" will pop-up a graph without having to go through
gv.  Also added --linestyle as an option.  All these changes were
submitted by Dominique Orban.  Thanks!

v0.3 (26 Mar 2003)
------------------

Change:

Added --sep option (submitted by Dominique Orban).
Force error exit if fewer than two solver files supplied.

v0.4 (10 Apr 2003)
------------------

Change:

Paulo Jose da Silva e Silva <rsilva@ime.usp.br> pointed out that
(the super nifty) syntax

      file = open(fname, 'r')
      for line in file:
	  ...

unfortunately isn't compatible with Python versions <= 2.1.  Now using
a more conventional syntax.

v0.5 (24 Apr 2003)
------------------

Change:

More suggestions from PJSS:

1. Added a small number to maxrat, so as not to hide any changes at a
profile tip.

2. Now stripping before splitting.  Otherwise, initial blankspace
would force an extra column.
