Topkg is a packager for distributing OCaml software. It provides an API to describe the files a package installs in a given build configuration and to specify information about the package's distribution creation and publication procedures.
The optional topkg-care package provides the
topkg command line tool
which helps with various aspects of a package's life cycle: creating
and linting a distribution, releasing it on the WWW, publish its
documentation, add it to the OCaml OPAM repository, etc.
Topkg is distributed under the ISC license and has no dependencies. This is what your packages will need as a build dependency.
