Impressario Message Catalog Header File So that Impressario and impr_desktop products can be built standalone and so that the distributed Impressario library source code will build, a copy of the most current uxsgiimpr.h header file is checked in the latest impressario trees. Currently, the only living tree is the main OS tree (kudzu). If you add a message to the catalog make sure to check in a copy of the updated uxsgiimpr.h in: /proj/<latest OS>/isms/impressario/include/msgs
