# This handles SVGs PNGs and ASCII outputs.
# It handles included files with the .iuml extension: !include foo.iuml
# All diagrams have the .puml extension and reside in the diagrams directory
# All output is saved to the output directory
#
# make svg    - (default) build all diagrams as SVGs
# make png    - build all diagrams as PNGs
# make ascii  - build all diagrams as ACII Art text files (.atxt)
# make all    - build SVG, PNG, and ASCII files
# make depend - build the dependency cache (also done automatically)
# make clean  - clean up build artifacts and output files
#
# Diagrams can be built in parrallel with `make -j`.

# If you installed plantuml from Homebrew (brew install plantuml) use this:
# PLANTUML = plantuml
PLANTUML = plantuml
