##
## This script recursively goes through the matlab directory and its
## subdirectories in the unstable branch, comparing the calling structures of the
## functions to those in another branch/commit, in this case the 4.2.5 branch
## The output is compatible with a Dynare Wiki page
##
## NB: To err on the side of safety, this script won't clean your workspace so a
## git command to checkout a different branch will fail if your workspace is
## dirty.
