+* WHAT IS ASTERISK
+ Asterisk is an Open Source PBX and telephony toolkit. It is, in a
+sense, middleware between Internet and telephony channels on the bottom,
+and Internet and telephony applications at the top. For more information
+on the project itself, please visit the Asterisk home page at:

+
+* REQUIRED COMPONENTS
+
+== Linux ==
+ Currently, the Asterisk Open Source PBX is only known to run on the
+Linux OS, although it may be portable to other UNIX-like operating systems
+as well.
+

+
+ If you want to use format_wav module, then you need a very recent
+version of libaudiofile (at least version 0.2.0, or you can apply the
+following patch to version 0.1.9):
