`~/.matlab/R2012a/mexopts.sh` for Mac OS X 10.8 with homebrew. via <http://bastibe.de/matlab-mex-homebrew-and-os-x-108-mountain-lion.html>
#
# mexopts.sh Shell script for configuring MEX-file creation script,
# mex. These options were tested with the specified compiler.
#
# usage: Do not call this file directly; it is sourced by the
# mex shell script. Modify only if you don't like the
# defaults after running mex. No spaces are allowed
# around the '=' in the variable assignment.
#
# Note: For the version of system compiler supported with this release,
# refer to the Supported and Compatible Compiler List at:
# http://www.mathworks.com/support/compilers/current_release/
#
#
# SELECTION_TAGs occur in template option files and are used by MATLAB
# tools, such as mex and mbuild, to determine the purpose of the contents
# of an option file. These tags are only interpreted when preceded by '#'
# and followed by ':'.

Thanks a tonne! This gist helped me figure out a bug in the mexopts.sh file! 👍
