+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.
