<BLOCKQUOTE>
where <I>option</I> may be one of the following:
<DL>
<DT> <B>all</B>
<DD> Extract the root cell and all its children. This bypasses
the incremental extraction and ensures that a new <TT>.ext</TT>
file is written for every cell definition.

<DD> Extract the indicated cell into file <I>name</I>
<DT> <B>do</B>|<B>no</B> [<I>option</I>]

may be one of the following:

<DD> List the cell and all parents of selected cell. Note that
this is not really an extract option and is superceded by
the <B>cellname</B> command.
<DT> [<B>list</B>|<B>listall</B>] <B>style</B> [<I>stylename</I>]
<DD> Set the current extraction style to <I>stylename</I>.
Without arguments, print the current extraction style.
With keyword <B>list</B>, return the current extraction
style as a Tcl result. With keyword <B>listall</B>, return
all valid extraction styles for the technology as a Tcl
list.

<H3>Summary:</H3>
<BLOCKQUOTE>
With no options given, the <B>extract</B> command incrementally
extracts the root cell and all its children into separate
<TT>.ext</TT> files. With options, the effect is as described
in the Usage section above.
</BLOCKQUOTE>
<H3>Implementation Notes:</H3>
<BLOCKQUOTE>
<B>extract</B> is implemented as a built-in <B>magic</B> command. <P>
<B>ext</B> is an alias for command <B>extract</B> (allowed
abbreviation where the usage would otherwise be ambiguous).
