-@chapter Plan 9
-
-The native @uref{http://plan9.bell-labs.com/plan9/, Plan 9} compiler
-does not implement all the C99 features needed by FFmpeg so the gcc
-port must be used.  Furthermore, a few items missing from the C
-library and shell environment need to be fixed.
-
-@itemize
-
-@item GNU awk, grep, make, and sed
-
-Working packages of these tools can be found at
-@uref{http://code.google.com/p/ports2plan9/downloads/list, ports2plan9}.
-They can be installed with @uref{http://9front.org/, 9front's} @code{pkg}
-utility by setting @code{pkgpath} to
-@code{http://ports2plan9.googlecode.com/files/}.
-
-@item Missing/broken @code{head} and @code{printf} commands
-
-Replacements adequate for building FFmpeg can be found in the
-@code{compat/plan9} directory.  Place these somewhere they will be
-found by the shell.  These are not full implementations of the
-commands and are @emph{not} suitable for general use.
-
-@item Missing C99 @code{stdint.h} and @code{inttypes.h}
-
-Replacement headers are available from
-@url{http://code.google.com/p/plan9front/issues/detail?id=152}.
-
-@item Missing or non-standard library functions
-
-Some functions in the C library are missing or incomplete.  The
-@code{@uref{http://ports2plan9.googlecode.com/files/gcc-apelibs-1207.tbz,
-gcc-apelibs-1207}} package from
-@uref{http://code.google.com/p/ports2plan9/downloads/list, ports2plan9}
-includes an updated C library, but installing the full package gives
-unusable executables.  Instead, keep the files from @code{gccbin.tgz}
-under @code{/386/lib/gnu}.  From the @code{libc.a} archive in the
-@code{gcc-apelibs-1207} package, extract the following object files and
-turn them into a library:
-
-@itemize
-@item @code{strerror.o}
-@item @code{strtoll.o}
-@item @code{snprintf.o}
-@item @code{vsnprintf.o}
-@item @code{vfprintf.o}
-@item @code{_IO_getc.o}
-@item @code{_IO_putc.o}
-@end itemize
-
-Use the @code{--extra-libs} option of @code{configure} to inform the
-build system of this library.
-
-@item FPU exceptions enabled by default
-
-Unlike most other systems, Plan 9 enables FPU exceptions by default.
-These must be disabled before calling any FFmpeg functions.  While the
-included tools will do this automatically, other users of the
-libraries must do it themselves.
