--------------------------------------------------------------------------------
gmt 1.1-1 (2007-08-02)
--------------------------------------------------------------------------------
o Improved psxy(), pstext(), and psclose() so they no longer expect a
  Mercator-projected map, but any kind of map.

o Simplified gmt.system(), thanks to improved system() in R 2.5.0.




--------------------------------------------------------------------------------
gmt 1.1-0 (2007-07-29)
--------------------------------------------------------------------------------
o Added function num2deg() to convert numeric to degrees, the opposite of
  deg2num().

o Changed gmt() so quiet=TRUE by default, and files .gmtcommands4 and
  .gmtdefaults4 are created in dirname(file) instead of R working directory.

o Changed psxy(), pstext(), and psbar() so temporary GMT input files are saved
  directory dirname(tempdir()) instead of R working directory. These temporary
  files are later removed by psclose().

o Changed psclose() so the bounding box declaration is moved to the postscript
  file header, and GMT input files are removed from temporary directory. If
  cleanup=TRUE, the files .gmtcommands4 and .gmtdefaults4 are also removed.

o Improved r2gmt() to support # commented table header.

o Added scripts example.bat and example.sh that mimic the behaviour of the 'gmt'
  package.

o Improved help page examples.

gmt 1.0-1 (2005-10-01)
--------------------------------------------------------------------------------
o Improved performance by changing approach from shell("cmd>file") to
  ps<-system("cmd");writeLines(ps,file). Demo runs four times faster.

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
gmt 0.9-1 (2005-09-27)
--------------------------------------------------------------------------------
o Added argument 'ref' to psbar() to standardize bar height.

o Added function gmt() to initialize GMT session, making .gmthome(),
  gmtdefaults, and gmtset() obsolete. The package assumes that binaries are in
  the PATH and GMTHOME is defined.

o Added function r2gmt() to write GMT input files, making .data2gmt() and
  .file2gmt() obsolete.




--------------------------------------------------------------------------------
gmt 0.9-0 (2005-09-25)
--------------------------------------------------------------------------------
o Added functions .data2gmt(), .file2gmt(), .gmthome(), deg2num(), geodist(),
  gmt(), gmtdefaults(), gmtset(), psbar(), psclose(), pscoast(), pstext(), and
  psxy().

o Added example objects demo.bar, demo.coast, demo.set, demo.text, and demo.xy.
