- Renamed old Vcopy.py to OldVcopy.py, some cosmetic changes to it (is
  it still needed?)
- Added new Vcopy.py which does everything that Vtime.py does but also
  format conversions, image scaling, and packfactors.
- VFile: make packfactor always a tuple; introduce set and get methods
  for pf, format, and calculate some derived values.
- Added new module GET.py to std library, use it instead of defining
  DM* in VFile.
- Get rid of C programs (new Python programs can do all that they do
  and they probably don't understand the current file format anyway).

get rid of testpackfactor(): not longer necessary

* Added libwww entry to Makefile.
* Documented new array module.
* Documented extensions to regex (last, substring, translation table).

Dsend - Main program analogous to Vsend to send data from display

  accordingly: SetMin, SetMax, SetDefault are no longer methods of the
  compressor/decompressor but are functions of the cl module and they
  take a first argument which is a compression scheme

Vedit.py, VeditForm.fd: added scroll bar, Trunc, layout rearrangement.
Viewer.py: added random access, qinfo() function.

  way); more efficiently check whether parameters are float; removed
  one argument from DecompressImage method; use clGetParam instead of
  clGetParams where it makes sense; convert int parameters in
  SetParams, SetParam, SetMin, SetMax, and SetDefault to float when
  needed; added QuerySchemeFromHandle method
* Makefile: interchanged cstubs and cgen.py so that $> in rule gets
  them in the right order

Vrecb.py: use the new interfaces to imageop (fix -M, -m, -g options).

will try to coerce anyway.
classobject.c: instance 'nonzero' should first try __nonzero__
only then __len__.

  listfontnames, bitmap ops.
* listobject.c: use mkvalue() when possible; avoid weird error when
  calling append() without args.
* modsupport.c: new feature in getargs(): if the format string
  contains a semicolor the string after that is used as the error
  message instead of "bad argument list (format %s)" when there's an
  error.

Removed duplicate description of -r option from documentation file.

algorithms in cl module.
aifc.py: fixed a small bug.

* Fixed memory leaks in socket, select and sv modules: mkvalue("O", v)
  does INCREF(v) so if v is brand new it should be XDECREF'd
