/**********************************************************************
* REXXAPI.C *
* *
* This program adds a ZIP engine directly to the REXX language. *
* The functions are: *
* UZDropFuncs -- Makes all functions in this package *
* unknown to REXX. *
* UZLoadFuncs -- Makes all functions in this package *
* known to REXX so REXX programs may *
* call them. *
* UZFileTree -- Searches for files matching a given *
* filespec, including files in *
* subdirectories. *
* UZUnZip -- Unzip command-line entry point. *
* This is functionally equivalent to *
* using Unzip as an external program. *
* UZUnZipToVar -- Unzip one file to a variable *
* UZUnZipToStem -- Unzip files to a variable array *
* UZVer -- Returns the Unzip version number *
* *
