// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Now unzip to the "test" subdirectory, under our current
// working directory:

if li_NumFilesUnzipped < 0 then
    Write-Debug loo_Zip.LastErrorText

// The filenames within the .zip are unchanged, but it unzipped
// test/hw.pl and test/hamlet2.xm
