Installs Ghostscript on Heroku. Currently using Ghostscript 10.06.0.

Add this buildpack to your Heroku app:

heroku buildpacks:add https://github.com/commandpostsoft/heroku-buildpack-ghostscript.git

Or with multiple buildpacks, create a .buildpacks file:

https://github.com/heroku/heroku-buildpack-ruby.git
https://github.com/commandpostsoft/heroku-buildpack-ghostscript.git

./build/release.sh           # Update to latest version
./build/release.sh 10.06.0   # Update to specific version

This script automatically:

• Checks if a precompiled release already exists
• If yes: updates bin/compile to use it (fast)
• If no: builds from source, uploads release, then updates (slower, requires Docker)

• GitHub CLI (gh) - brew install gh
• Docker (only needed if building a new version)

For more control, you can run the steps separately:
