* tconv [-b] [-c [-OUGd]] [-i] [-B [-D dir]] [-I] [-k] [-V] [-t term] [file]
*
* -c convert from termcap
* -i convert from terminfo source
* -b convert from terminfo binary
* -B convert to terminfo binary
* -I convert to terminfo source
* -V print version info
*
* The following switches are available when converting from termcap:
* -d don't supply any defaults for missing capabilities
* -O include obsolete termcap capabilities
* -G include GNU capabilities
* -U include UW capabilities
*
* -k keep comments
* -D dir directory to put terminfo binaries in
*
* -t term name of terminal to translate
* file filename of termcap/terminfo database to use
*
* If a file is specifed and no terminal is given the entire file we be
* translated.
* If no terminal and no file is specified then the terminal name will be
* taken from the environment variable TERM.
* Unless compiling to a terminfo binary, output is to stdout.
