Q:

Custom buildpack for zip in Heroku

I would like to use the zip system command in Heroku, but it is not available. I don't understand how to write a custom buildpack by myself. Could someone please point me to an existing buildpack for zip or write a new one for me? In this thread, John Beynon wrote a custom buildpack for the wget command.

A:

Zipping you can do with pure ruby, I did it myself last week to zip a folder recursively using https://github.com/aussiegeek/rubyzip
