This package consists of a library with one entry point that allows an Intrinsics (or Xt) based application to be executed from a script file. In particular, applications based on the Athena and the Motif toolkits can be played. The script files are written in the tcl language, but for most applications this will just be a sequential set of instructions which will make the widgets in the application perform actions such as button clicks, list selection, text entry, etc.
