-Quicktime for Linux
-
-Author: Adam Williams quicktime@altavista.net
-Homepage: heroinewarrior.com/quicktime
-Requires: libpthread
-------------------------------------------------------------------------
-
-*****
-
-This is a Quicktime library for UNIX in a freely redistributable,
-statically linkable library. You can statically link it in a program
-and charge money for the program. The only condition is that if you
-use it in a program, you must put the author's name and email
-somewhere. If you improve the library itself or add a free codec to
-it, you should release your improvements. If you redistribute the
-code, you must also redistribute the author information and
-documentation. At this time it's very popular to license stuff under
-the GPL. You are free to include this library in a derived work and
-license the derived work under GPL.
-
-*****
-
-Building:
-type "make" in the quicktime/quicktime directory.
-type "make util" to get some Small Utilities.
-
-Configuration:
-
-The file "config.h" defines the size of a 16 bit word and what the
-maximum file size is.
