PGSBOX version 3.1 (2003/04/29)
-------------------------------

* Added a C wrapper function, cpgsbox(), and C test/demo program, cpgtest,
  which duplicates PGTEST and serves as a C coding template.

* Added calendar date axes.

* Sped up the max/min search - if only tickmarks are required there is no need
  to search the interior of the image.

* Return margin widths in CACHE(,NC).

* Fixed a buglet which caused ticks at the frame edges to be skipped.

* Return error 3 if CACHE overflows.

Support routines:

* Adapted PGWCSL for WCSLIB 3.x - it is now a C function (for interfacing to
  WCSLIB) with a FORTRAN-like interface (for PGSBOX).
