Info-ZIP UnZip

Info-ZIP UnZip

History
Info-ZIP's UnZip it was originally based on the Unzip DOS program that Samuel H. Smith had created a year earlier. But due to licensing restrictions it was soon completely rewritten.

Early releases were based on the source code provided with Samuel H. Smith's freeware UNZIP program but since that code contained a no commercial usage clause which clashed with the Info-ZIP's stated aim to make ZIP available to everyone this was soon replaced with a code released under a very permissive ad hoc licence and the Info-ZIP code soon started showing up in other projects.

Features
On OS/2 you can also get Info-ZIP UnZip in the form of a REXX compatible dynamic link library which makes coding using it even simpler as long as your language has REXX DLL compatibility as in the case of Perl or if you write a simple DLL wrapper in your code.
