+ Unzip will list, test, or extract files from a ZIP archive, commonly
+ found on MS-DOS systems.  The default behavior (with no options) is to
+ extract into the current directory (and subdirectories below it) all
+ files from the specified ZIP archive. Unzip is compatible with
+ archives created by PKWARE's PKZIP, but in many cases the program
+ options or default behaviors differ.
+
+ Zipinfo lists technical information about files in a ZIP archive, most
+ commonly found on MS-DOS systems.  Such information includes file access
+ permissions, encryption status, type of compression, version and operating
+ system or file system of compressing program, and the like.
+
+ Funzip acts as a filter; that is, it assumes that a ZIP archive is
+ being piped into standard input, and it extracts the first member from
+ the archive to stdout.  If there is an argument, then the input comes
+ from the specified file instead of from stdin.
+
+ Unzipsfx is a modified version of unzip designed to be prepended to
+ existing ZIP archives in order to form self-extracting archives.
+ Instead of taking its first non-flag argument to be the zipfile(s) to
+ be extracted, unzipsfx seeks itself under the name by which it was
+ invoked and tests or extracts the contents of the appended archive."
