# gccopts.sh   Shell script for configuring MEX-file creation script,
#               mex.
#
# 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: only the gcc side of this script was tested.
#               The FORTRAN variables are lifted directly from
#               mexopts.sh; use that file for compiling FORTRAN
#               MEX-files.
#
# 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 ':'.
