-# When called with no arguments, this shell script builds the Go database,
-# which is somewhat minimal for size reasons (it only contains the most
-# commonly used entries), and then builds the complete JSON database.
-#
-# To limit the action to only building one or more terminals, specify them
-# on the command line:
-#
-#  ./mkdatabase xterm
-#
-# The script will also find and update or add any terminal "aliases".
-# It does not remove any old entries.
-#
-# To add to the set of terminals that we compile into the Go database,
-# add their names to the models.txt file.
-#
-
-# This script is not very efficient, but there isn't really a better way
-# without writing code to decode the terminfo binary format directly.
-# Its not worth worrying about.
-
-# This script also requires bash, although ksh93 should work as well, because
-# we use arrays, which are not specified in POSIX.
