# Serialization module for shoop. Expands the OBJECT class with a serialize
# method, that can dump out machine-readable definitions of objects.
#
# For example: FOO . serialize > FOO.sh; exit
# To restart: . ./FOO.sh

## restore their internal values, then include this into your shoop
## script. Any object that you then wish to save should then be done
## with the following syntax:

## C<FOO . serialize &E<gt> save_FOO.sh>
# Enable introspection inside _shoop
