Well, the matplotlibrc file is checked for when the python process is
started, and the current directory when matplotlib is imported is
used. Since we launch the build process in the doc directory next to
make.py, doc is the current working directory when the plot directive
extension is imported and this is used to build the examples. So it
is not the directory that the example is in that is important, but the
current directory when matplotlib is imported.
On import the matplotlib.rc_params function is called to set
matplotlib.rcParams. The rc_params function in turn calls
matplotlib_fname, which does the following search
* current working dir
* environ var MATPLOTLIBRC
* HOME/.matplotlib/matplotlibrc
* MATPLOTLIBDATA/matplotlibrc
Hope this helps!
