    for a full list of changes.
  * Bug fixes:
  - Replaced the obsolete ftime() function with clock_gettime()
    when the latter is available (gh#vermaseren/form#276)
  - Improved the algorithms of division and reminder for
    non-monic multivariate polynomials (gh#vermaseren/form#281)

  - Fixed crashes in routines for gzip decompression
    (gh#vermaseren/form#95)

  - Fixed a crash on accessing the first
    gh#vermaseren/form#factdollar factor of an integer
    (gh#vermaseren/form#222)
  - Fixed memory leaks in routines for gzip compression

    (gh#vermaseren/form#272)
  - Fixed transform,addargs for the case that the result becomes
    0 (gh#vermaseren/form#277)
  - Fixed some bug in LHS patterns with poly(rat)fun and symbols
  - Fixed the problem that content_ did not handle functions
    properly
- Disable documentation due to LaTeX errors.

- compile independent of build system CPU (boo#1100677)

- Setup MPI environment before building.

- Update to version 4.2.0:
  + See
    https://github.com/vermaseren/form/wiki/Release-Notes---Form-4.2.0
    for list of changes.
- Drop form-devref-pdf.patch; incorporated upstream.
- Add BuildRequires on git, required to ascertain revision id.

- Initial package.
- Add form-devref-pdf.patch to fix a typo preventing devref PDF
  documentation from generating.
- Add %{name}-rpmlintrc file to suppress warning regarding missing
  man pages: upstream doesn't supply these.
