<H1> 2. Introduction </H1>
<!--docid::SEC3::-->
Zsh is a UNIX command interpreter (shell) usable as an interactive
login shell and as a shell script command processor. Of the standard shells,
zsh most closely resembles <CITE>ksh</CITE> but includes many enhancements. Zsh
has command line editing, builtin spelling correction, programmable
command completion, shell functions (with autoloading), a history
mechanism, and a host of other features.

Zsh was originally written by Paul Falstad <TT><pf@zsh.org></TT>.
Zsh is now maintained by the members of the zsh-workers mailing
list <TT><zsh-workers@sunsite.dk></TT>. The development is currently
coordinated by Peter Stephenson <TT><pws@zsh.org></TT>. The coordinator
can be contacted at <TT><coordinator@zsh.org></TT>, but matters relating to
the code should generally go to the mailing list.

<H2> 2.6 The Zsh Userguide </H2>
<!--docid::SEC9::-->
A userguide is currently in preparation. It is intended to complement the
manual, with explanations and hints on issues where the manual can be
cabbalistic, hierographic, or downright mystifying (for example, the word
`hierographic' does not exist). It can be viewed in its current state at
<TT>http://zsh.sunsite.dk/Guide/</TT>. At the time of writing, chapters
dealing with startup files and their contents and the new completion system
were essentially complete.
