/opt/openjp2-svn on a linux system. The location of the configuration file
is platform-dependent (of course). If you use either linux or mac, the path
to the configuration file would normally be ::
$HOME/.config/glymur/glymurrc
but if you have **$XDG_CONFIG_HOME** defined, the path will be ::
$XDG_CONFIG_HOME/glymur/glymurrc
On windows, the path to the configuration file can be determined by starting up Python
and typing ::
import os
os.path.join(os.path.expanduser('~'), 'glymur', 'glymurrc')

-------
The only configuration I've tested is Python(xy), which uses Python 2.7.
Python(xy) already comes with numpy, but you will have to install pip and then
contextlib2 and mock as well. Glymur seems to work with both 1.5.1 and the
svn development versions of openjpeg.
I would recommend using WinPython, but Python(xy) also seems to work. WinPython 3.3
should work with no additional installations required, but 2.7 versions still require
contextlib2 and mock to be installed via pip.

tests.
* **OPJ_DATA_ROOT** - points to directory for OpenJPEG test data
* **FORMAT_CORPUS_ROOT** - points to directory for format-corpus repository (see https://github.com/openplanets/format-corpus)
* **FORMAT_CORPUS_ROOT** - points to directory for format-corpus repository (see https://github.com/openplanets/format-corpus if you wish, but you really don't need to bother with this)
Setting these two environment variables is not required, as any tests using
either of them will be skipped.
