<p>I would like to use the 7-Zip DLLs from Delphi but have not been able to find decent documentation or examples.  Does anyone know how to use the 7-Zip DLLs from Delphi?</p>

As of release 1.102 the
JEDI Code Library
has support for
7-Zip
built into the
JclCompression
unit. Haven't used it myself yet, though.
