ditaa is a small command-line utility that can convert diagrams drawn using ascii art ('drawings' that contain characters that resemble lines like | / - ), into proper bitmap graphics. See http://www.ditaa.org

results from the current version of the Go port (in progress) can be compared visually side-by-side with results from the original at: http://akavel.github.io/ditaa

the Go fork of ditaa is "dual-licensed": you can use it under terms of either:

• GPLv2 or (at your option) any later version; or
• LGPLv3 or (at your option) any later version. (it was forked at the point where the original Java codebase was switched from GPLv2+ to LGPLv3+)
