# Generate a dot file to create graph of RERO-ils data (orga, lib and users)
#
# Usage:
# bash gen.sh output.dot
# where `output.dot` is the output file that permit to generate a graph.
# To generate the graph:
# dot -Tsvg output.dot -o organisations.svg
# where `output.dot` is the previous file. And `organisations.svg` the final schema you want to display.
