Remove unmaintained lang/drscheme port, which is superceded by
lang/plt-scheme. According to pointyhat lang/drscheme it has been
broken since 2007/06.

Upgrade to v370.  The port now unconditionally depends on Cairo
graphics.  Additional upstream changes include:
 - The conservative garbage collector (CGC) has been replaced with a
   precise garbage collector (3m) in the standard build.  For most
   users, this change simply amounts to "better performance in space
   and time".  Use the port knob 'CGC' to build DrScheme with
   the conservative garbage collector.
 - Unit-based servlets are no longer supported in the web server.
   Use module-based servlets, instead.
 - A new `(lib "unit.ss")' library replaces the old one and provides
   a simpler and more flexible syntax.
 - The HtDP "world.ss" and "image.ss" teachpacks have been revised,
   including support for the creation of animated GIFs and DrScheme's
   teachpack GUI now works only with the HtDP languages.  In other
   languages, use `require' to access teachpacks.

Upgrade to v360.  Upstream changes include:
 - A new macro stepper that traces through macro expansion
   step by step.
 - A new "Lazy Scheme" language level.
 - New support for prompts and composable continuations.
 - Regexp support now includes the usual collection of
   "Perl-compatible" features.
 - Compiler improvements and bug fixes.

- Upgrade to v352.  This is a bug-fix release.
- Tweak the port's build to detect and use libpng and
  libjpeg present in $LOCALBASE.
- Build this port for the amd64 architecture in addition to i386.

Update to v351.

Upstream changes include:
 - bug-fixes,
 - improved 3m performance,
 - HtDC libraries have been reorganized into four packages,
 - improvements to the 'Debug' button, including persistent
   breakpoints,
 - expressiveness improvements and a 2x performance boost
   for tight loops that do a lot of contract checking.

Upgrade to v350.

Major changes include:
 - A new JIT compiler for mzscheme.
 - The installed port uses a hier(7)-compatible directory
   structure under ${PREFIX}.
 - ProfessorJ includes a unit-testing mechanism.
 - The default exception handler in mzscheme now shows
   stack-trace information.

The port now offers a new option 'MMM' that builds DrScheme with
the experimental 3M garbage collector.

Upgrade to v301 --- bug fixes and changes to the demos.

- Upgrade to v300.  This DrScheme release offers Unicode support,
  a foreign function interface, anti-aliased text, and many other
  extensions and improvements.

- Add a port knob 'CAIRO' to conditionally allow compilation with
  the Cairo graphics library.

Add SA256 checksums.

Upgrade to v209.

Upgrade to v208.

Upgrade to v206p1.  Mark as 'only for i386', till the ports to other
Tier-1 architectures are completed.

Update to v205.

Upgrade to v204.

Update to v203.

Correct ${MASTER_SITE}, update checksums.

Submitted by:   Paul Gabriel <paul@pogo.franken.de>

Move downloaded distfile to a directory numbered by ${PORTVERSION} to
compensate for the fact the master tarball does not have a version
number in its filename.  This prevents older copies of the sources
being picked up during the "fetch" phase.

Update to v202.

Upgrade to v200.

Requested by:   Austus <austus@adelphia.net>

Upgrade to v103p1.    

A port of `DrScheme', a graphical teaching environment and IDE for Scheme.
