-The fetchmail code was developed under Linux, but has also been extensively
-tested under the BSD variants, AIX, HP-UX versions 9 and 10, SunOS, Solaris,
-NEXTSTEP, OSF 3.2, IRIX, and Rhapsody.
-
-It should be readily portable to other Unix variants and Unix-like operating
-systems (it uses GNU autoconf). It has been ported to Cygwin, LynxOS and BeOS
-and will build there without special action. It has also been ported to QNX;
-to build under QNX, see the header comments in the Makefile. It is reported to
-build and run under AmigaOS.
