opam-build-revdeps - Build reverse dependencies of a package in OPAM.

opam-build-revdeps builds the reverse dependencies of a given OPAM package. It can also build two different versions of the same package, in order to compare the results.

This program has been designed to test what can other packages can break in OPAM, if we inject a new version. It was specifically targeted to check OASIS reverse dependencies.

See the file INSTALL.md for building and installation instructions.
