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