# This function was first imagined and implemented by Thomas Mansi
#
# All I did was make it more global, so that you can call it from any script.
# To do so, in your script you must first source this file:
#
# source ${fullpath}/my_do_cmd
# This is the equivalent of perl's usepackage, python's use, or C++'s include.
#
# 
# Then you can call your command by pre-pending do_cmd, as in:
#
# do_cmd mincinfo yourfile.mnc
# 
# Important note: If your command has quotes at some points, this will not work properly,
# as is the case with minccalc -expr "some_expresion".
