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