# flex2netbsd:  convert a flex tree into a
# netbsd flex source tree, under src/external/bsd/flex/dist,
# based on flex2netbsd by Bernd Ernesti and changes by Simon Burge
#
# Rough instructions for importing new flex release:
#
#	$ cd /some/where/temporary
#	$ tar xpfz /new/flex/release/tar/file
#	$ sh /usr/src/external/bsd/flex/dist/flex2netbsd flex-2.6.x
#	$ cd flex-2.6.x
#	$ cvs import -m "Import flex 2.6.x" src/external/bsd/flex/dist FLEX flex-2-6-x
#	$ run ./configure
#	$ run make
#	check the config file and copy it to /usr/src/external/bsd/flex/include
#	check the manual page against our copy if there are new options and
#	update
#	build the initparse.c and initscan.c without line numbers in src/dist
#	and commit them:
#       - nbyacc -l -d -o initparse.c parse.y
#	- nblex -L -t -p scan.l > initscan.c
