FTP to nesl.scandal.cs.cmu.edu (currently 22.214.171.124), login as anonymous, enter your e-mail address as the password, cd code/nesl, and get nesl.tar.Z. Depending on your FTP client you may need to set the transfer mode to binary first. Finally, uncompress and untar the file.
The system requires about 3.5 Megabytes of disk space uncompressed and without binaries. Some of this can be removed if you are not going to be using all of the parallel machines (see the cvl directories in the next section), or if you don't need to keep the manuals. The biggest use of space will be for the dumped Common Lisp image you will make after building NESL; this will occupy from 3 to 35 Megabytes, depending on the version of Lisp you use and the machine on which you are running (see the discussion of building the system in Section 5.3).% ftp nesl.scandal.cs.cmu.edu Name: anonymous Password: email@example.com ftp> cd /afs/cs/project/scandal/public/code/nesl ftp> binary ftp> get nesl.tar.Z ftp> quit % uncompress nesl.tar % tar -xf nesl.tar
