IPMETRICS Ipmetrics converts Interpress metric masters to the form need by specific composition systems. HOW TO ADD A NEW COMPOSITION SYSTEM To make it easier to add new output capability to ipmetrics, the interface from the executor has been simplified. Each composition system that is supported by ipmetrics is listed in the file "conf.c". Basically, for eack system three procedures are provided: one that is called for initialization one that is called for each property vector one that is called to clean-up In addition, a boolean flag is given to determine whether a configuration file should be read from the standard input or not. If the configuration file is read, then it is placed in a linked list of structures. The structures are defined in "config.h". The initialization and clean-up procedures are called with a pointer to the chain of font descriptors. The procedure to handle each vector is called with the configuration chain and the vector.
