30 # Terminal Info Generator
31 #
32 # This script generates a static terminfo database for use by mdb. For each
33 # of the terminal properties used by mdb_termio.c, this script uses tput(1)
34 # to determine the value of the given attribute for each specified terminal
35 # type. The script produces an ANSI-C source file which contains a static
36 # array for each terminal type storing the properties. An additional array
37 # is then declared containing a list of the terminal types and pointers to
38 # the previous arrays. Finally, source code for several terminfo routines
39 # are included that simply access the arrays and return the saved properties.
