<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.

<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).
