The Package Repository Server , which is currently part of the Eagle project, allows users to add, manage, and obtain packages for both Tcl and Eagle. All package information present on the server must be signed using either OpenPGP or Harpy.
It is implemented as a set of TH1 (and Tcl) scripts running on a carefully configured instance of Fossil. All data necessary to run the repository server is stored in a SQLite database.
Also see the Package Repository Client and Package Downloads Server.
