  ONLY THE FIRST TIME YOU INSTALL THIS CODE, you need to patch a
   few system files with the hooks for pgm using the patchfile
   named kpgm-<YOUR_OS_RELEASE>-<date>.patch
   The files affected are at most the following
	/sys/conf/files
	/sys/conf/options
	/sys/netinet/in.h
	/sys/netinet/in_proto.c
   
   To patch your system sources, do the following

	cd /
	patch < YOUR_PATCH_FILE
   
everytime you install a new release, replace the files indicated
 below with the ones coming from the archive:

 * copy the following four files to /sys/netinet
	pgm.h pgm_var.h pgm_timer.c pgm_usrreq.c

 * copy the following two files to /usr/include/netinet
	pgm.h pgm_var.h

 * copy the following file to /usr/share/man/man4
	pgm.4

To compile a pgm-enabled kernel you need to put

	options PGM

in your kernel config file, then use the usual sequence to build a
kernel (config, make depend, make).
