You have a seperate executable for each and every little task? Such as, for instance, draw_line.sh so to draw a line, you do ./draw-line.sh row col row col? No wonder it's slow.

Imagine it this way... If this were a visual basic script, it'd be loading visual basic, calling the draw line routine, and quitting visual basic each time you drew a line. This is not going to be fast no matter how you cut it, in any language.

You should put these routines into functions, instead. Load once, use many times. This could make it literally hundreds to thousands times faster.

DH_PYSUPPORT(1) 						  python-support						   DH_PYSUPPORT(1)

NAME
dh_pysupport - use the python-support framework to handle Python modules SYNOPSIS
dh_pysupport [debhelper options] [-V X.Y] [-X item [...]] [-n] [module dirs ...] DESCRIPTION
dh_pysupport is a debhelper program that will scan your package, detect public modules in /usr/lib/pythonX.Y/site-packages, and move them to the shared Python modules location. It will generate appropriate postinst/prerm scripts to byte-compile modules installed there for all available python versions. It will also look for private Python modules and will byte-compile them with the current Python version. You may have to list the directories containing private Python modules. If a file named debian/pyversions exists, it is used to determine the python versions with which the package can work. Appropriate dependencies on python-support, python and pythonX.Y are put in ${python:Depends}. The ${python:Versions} and ${python:Provides} optional substitution variables are made available as well. OPTIONS
module dirs If your package installs private python modules in non-standard directories, you can make dh_pysupport check those directories by passing their names on the command line. By default, it will check /usr/lib/$PACKAGE, /usr/share/$PACKAGE, /usr/lib/games/$PACKAGE and /usr/share/games/$PACKAGE -n, --noscripts Do not modify postinst/postrm scripts. -d This option is deprecated. -V X.Y Force private modules to be bytecompiled with the specific X.Y python version, regardless of the default python version on the system. -X item, --exclude=item Exclude files that contain "item" anywhere in their filename from being taken into account to generate the python dependency. It also excludes them from byte-compilation. You may use this option multiple times to build up a list of things to exclude. CONFORMS TO
Python policy as of 2006-08-10 SEE ALSO
debhelper(7) This program is a part of python-support but is made to work with debhelper. AUTHORS
