The project was renamed from osh to etsh in 2016.
The author himself was added as MAINTAINER for shells/osh as per request
in 2008.
However, it's reasonable to assume that they lost interest in the
package in the meantime.
In any case, we have shells/etsh now, making this an obsolete duplicate.
Es is an extensible shell. The language was derived from the Plan 9
shell, rc, and was influenced by functional programming languages, such as
Scheme, and the Tcl embeddable programming language. This implementation is
derived from Byron Rakitzis's public domain implementation of rc, and was
written by Paul Haahr and Byron Rakitzis.
Gash is a POSIX-compatible shell written in Guile Scheme. It provides
both the shell interface, as well as a Guile library for parsing shell
scripts. Gash is designed to bootstrap Bash as part of the Guix
bootstrap process. There are plans to develop Gash into a
general-purpose shell and tool for building interfaces between Scheme
and the shell.
Features of the shell
* Sophisticated enough to be used to build Bash.
* Has a nice colorized prompt.
* Includes all of the POSIX-specified "special" built-ins except for
`times'.
* Includes about half of the POSIX-specified "regular" built-ins
(see `gash/built-ins.scm' for details).
Features of the programming interface
* Parses Shell scripts into an AST.
* Provides a rudimentary interface for writing Shell-like Scheme
scripts.

---------------------------
The MASTER_SITES for shells/mudsh is invalid. The email
address of the submitter of the port is no longer valid.
The app itself is a single perl script with no author in it.
