+# By default, flex will be configured to generate 8-bit scanners only if the
+# -8 flag is given.  If you want it to always generate 8-bit scanners, add
+# "-DDEFAULT_CSIZE=256" to CPPFLAGS.  Note that doing so will double the size
+# of all uncompressed scanners.
+# 
+# If on your system you have trouble building flex due to 8-bit character
+# problems, remove the -8 from FLEX_FLAGS and the "#define FLEX_8_BIT_CHARS"
+# from the beginning of flexdef.h.
+#
+# To bootstrap lex, cp initscan.c to scan.c and run make.
