29# flex2netbsd:  convert a flex source tree into a
30# netbsd flex source tree, under src/external/bsd/flex/dist,
31# based on flex2netbsd by Bernd Ernesti and changes by Simon Burge
32#
33# Rough instructions for importing new flex release:
34#
35#	$ cd /some/where/temporary
36#	$ tar xpfz /new/flex/release/tar/file
37#	$ sh /usr/src/external/bsd/flex/dist/flex2netbsd flex-2.6.x
38#	$ cd flex-2.6.x
39#	$ cvs import -m "Import flex 2.6.x" src/external/bsd/flex/dist FLEX flex-2-6-x
40#	$ run ./configure
41#	$ run make
42#	check the config file and copy it to /usr/src/external/bsd/flex/include
43#	check the manual page against our copy if there are new options and
44#	update
45#	build the initparse.c and initscan.c without line numbers in src/dist
46#	and commit them:
47#       - nbyacc -l -d -o initparse.c parse.y
48#	- nblex -L -t -p scan.l > initscan.c
