The following procedure is suggested for installation of Hugs on a Unix machine. (Precompiled binaries are provided for common PC platforms, although similar installation procedures can be used for these machines if you have a suitable C compiler.) 0) Compile the interpreter by editing src/Makefile, by selecting the desired operating system/compiler configuration in src/prelude.h and by running make. Not all of the combinations listed in the prelude.h file have been tested recently, so please report any problems and updates to me. 1) Choose a directory for the Hugs files to go in, say /usr/local/Hugs and copy the lib and libhugs directories, together with the executable from step (1), into this directory. Ensure that these files have appropriate permission settings. If you like, you can copy the demos to this subdirectory also. 2) Edit the script file `Hugs' to point to the directory chosen in step (1) and to set any preferred command line arguments. Copy this script file into a suitable directory; your own bin directory, for example, or a system wide directory like /usr/local/bin.
