This is a Heroku buildpack
for installing Texlive scheme-minimal on heroku.
This buildpack is useless if used alone. See https://devcenter.heroku.com/articles/using-multiple-buildpacks-for-an-app to learn how to add this buildpack to an existing app.
heroku buildpacks:add --index 1 https://github.com/vyuh/heroku-buildpack-tlmgr
This buildpack looks for the file tl_pkg.txt in the app's root directory
and creates a portable TeX Live installation in $BUILD_DIR/TeXLive.
The installation only has packages included in the plain scheme.
It then and adds packages listed in the file tl_pkg.txt of the app.
If you want packages not included in a plain TeXLive distribution then
just add its name to tl_pkg.txt.
Example tl_plg.txt:
latex-bin
xypic
Note: The creation of the buildpack can last at most 15 minutes. Then it is forcibly stopped by heroku. Do not add too many packages.
