You should have the following files after you unzip the zip file (mutex.zip): - mutex.exe - termcap - mutex.tar - mutex.doc - readme (this file) Put mutex.exe and termcap together in a directory on your PC. You need to compile UNIX mutex. First, use your favorite communication program to transfer mutex.tar to UNIX. Second, run `tar -xf mutex.tar' in UNIX. Then type `make'. You should then have a compiled copy of `mutex' in UNIX. NOTE: mutex is developed under "gcc" and is probably compilable under "cc". Please read mutex.doc for further information.
