Scsh is a Unix shell in that is has significant syntax extensions to make writing Unix shell scripts easy (constructing pipelines, setting I/O redirection, conditional execution etc.). It also offers access to lower-level functionality like all Posix system calls, TCP/IP sockets and a full-featured regular expression library. This is embedded into a general-purpose programming language with real data types, extensive, syntactically clean control constructs and "real" quoting rules. Scsh is also a full implementation of R4RS Scheme with some non-standard behavior (required for scripting). As a result, a wide varity of exiting Scheme code can be used. The underlying Scheme implementation is a virtual machine for compact byte code. The name of the installed program is "scsh", the manpage is scsh(1), other documentation is in (/usr/local/)lib/scsh/doc. To load slib, install slib into /usr/local/lib/slib and run (load "slib-init.scm") in scsh. It requires no additional setup (paths or such). The emacs interface is in the original distribution in emacs/. For documentation see doc/user-guide.txt. WWW: http://www.scsh.net/ - Alexander Langer
