Instant Coffee is an effort to package Java related applications, libraries, etc. for the easy installation on Maemo Fremantle (N900). Examples of packaged applications are: OpenJDK (actually the icedtea version) [package], MicroEmulator [package], or Clojure [package]. Please note that I am not the author of those applications but only packaged those to ease the installation on the N900. Furthermore, some packages are essentially based on other existing packages e.g. from Debian and had been repackaged for the N900 to include “optification“.
The packages are created using simple shell scripts and Py2Deb or PyPackager respectively. You can find these scripts at the projects Maemo garage page: https://garage.maemo.org/projects/instant-coffee
