This is release 2.1 of flex - a beta release.
The flex distribution consists of the following files:
README This message

parse.y
scan.l
ccl.c
dfa.c
ecs.c flex sources
gen.c
main.c
misc.c
nfa.c
sym.c
tblcmp.c
yylex.c
initscan.c pre-flex'd version of scan.l
flex.skel skeleton for generated scanners
flex.1 manual entry
Changes Differences between this release and the previous one
COPYING flex's copyright
MISC miscellaneous stuff (e.g., old VMS Makefile) which
almost no one will care about
If you have installed a previous version of flex, delete it (after making
backups, of course). This will entail removing the source directory,
/usr/include/{flexskelcom,fastskeldef,flexskeldef}.h, and
/usr/local/lib/flex.{skel,fastskel}, if that's where you put the various
pieces.
Decide where you want to keep flex.skel (suggestion: /usr/local/lib) and
move it there. Edit "Makefile" and change the definition of SKELETON_FILE
to reflect the full pathname of flex.skel.
Read the "Porting considerations" note in the Makefile and make
the necessary changes.
To make flex for the first time, use:
make first_flex
which uses the pre-generated copy of the flex scanner (the scanner
itself is written using flex).
Assuming it builds successfully, you can test it using
make test
The "diff" should not show any differences.
If you're feeling adventurous, rebuild scan.c using various
combinations of FLEX_FLAGS, each time trying "make test" when
you're done. To rebuild it, do
rm scan.c
make FLEX_FLAGS="..."
where "..." is one of:
-c
-ce
-cm
-cfe
-cFe
and testing using:
make FLEX_FLAGS="..." test
Format the manual entry using
nroff -man flex.1

the first doesn't work)
