This tool tries to check the compliance of a package with the IPOL Software Guidelines. It is still experimental; some false errors may be detected, some violations may be ignored. Please report such issues to nicolas.limare@cmla.ens-cachan.fr for improvement. You can test it with (good and bad) package examples, and use these examples as an illustration of the guidelines. The source code of this test tool is available and has a command-line interface too.
