INSPECTOR -- examine Z-Machine files -- Roger Firth (roger@firthworks.com) +! +! V1.1 29Jan04 - removed misleading comment from generated XML +! V1.0 11Nov03 - first public release +! +! This program is strictly for the curious. It reads a compiled Inform 6 .z5 or .z8 game file +! and attempts to display its contents. +! +! The program is a standalone Glulx utility which does not used the Inform library files. +! To compile it, you will need to include on the command line: $MAX_STATIC_DATA=600000 +! and you will require the "infglk.h" header file. To run it, any Glulx interpreter should do. +! +! To make any sense of the XML data produced by the R command, you will require +! the Dia drawing program (http://www.lysator.liu.se/~alla/dia). Unix and Windows only. +! +! IMPORTANT NOTE: The program is much more restrictive than Ztools in the Z-Machine files that +! it will handle, and much less reliable. Its primary advantage is that, being written using +! the Inform language, it is readily amenable to being customized and extended. +! +! This program is copyright Roger Firth 2003-2004. Copying and distribution, with or without +! modification, are permitted in any medium without royalty provided the copyright notice and +! this notice are preserved. +! +! ================================================================================================= +!
