The files in this directory are intended to be used to put all parts of c4b
into the FreeBSD CVS source tree. It is not meant to easily incorporate c4b
into the source tree after a cvsup operation. The later is not needed any more
after restructuring the c4b source tree to completely compile outside the
FreeBSD source tree.

The "edit-*" files are hints how several system parts must be modified. The
main target is 7-CURRENT, but most changes should also apply to earlier
versions starting at 5.3-RELEASE.

Versions before 5.0-RELEASE are not supported any more by the current version
of c4b. After 5.0-RELEASE the system startup procedure has changed. The result
is that there is no startup script for versions before 5.1-RELEASE in the c4b
distribution.

Versions before 5.3-RELEASE may need some modification in the avmaic kernel
module. Only since 5.3-RELEASE the PC-CARD subsystem knows of the file
"pccarddevs.h". This affects ".../c4b/kernel/modules/avmaic/Makefile", as it
shall not contain "pccarddevs.h" in the SRCS variable on earlier systems.

The shell script "make-patches.sh" is something different. It is used to
create the basic patch files to make c4b known to i4b. It is called after
modifying the necessary files to create an updated patchset.
