How do I set the MANPATH mpich-3.0.4 on Debian Wheezy?
The installation location is /opt/mpich.
I tried in ~/.bashrc:
MANPATH = /opt/mpich/share/man:$MANPATH
export MANPATH
but not work.
I call 'man mpich', or is not that what you call the man of mpich?
I researched and not found.

However,
PATH=/opt/mpich/bin:$PATH
export PATH
worked.
