+SASH - a stand-alone shell with many built-in commands
+
+The sash program is a stand-alone shell which is useful for recovering
+from certain types of system failures.  In particular, it was created
+in order to cope with the problem of missing shared libraries or important 
+executables.
+
+Sash can execute external programs, as in any shell.  There are no
+restrictions on these commands, as the standard shell is used to execute 
+them if there are any non-wildcard meta-characters in the command.
+More importantly, however, is that many of the standard system commands
+are built-in to sash.
+
+This script applies the 'sash-plus-patches' command collection, which
+adds the following commands: 'chroot' 'pivot_root' and 'losetup'.
+
+These functions actually provide interfaces to the respective Linux system
+calls. They are specificly useful when sash is used as a shell in "initial
+ramdisk" (initrd) environments.
+
+In addition, a simple shell variable expansion support has been added, e.g.
+the variable "$(VAR)" is replaced by the content of the variable "VAR".
