1.1     ! root        1: @(#)README     1.3
        !             2: 
        !             3: The files in this directory with the .ti suffix are terminfo sources.
        !             4: They should be compiled (separately or by catting them together into
        !             5: terminfo.src) with tic, placing the results in /usr/lib/terminfo/?/*.
        !             6: 
        !             7: The cvt files are useful tools for converting termcap to terminfo.
        !             8: They are not 100% accurate, but do most of the conversion for you.
        !             9: cvt.ex is an ex script to convert a termcap description into a
        !            10: terminfo description.  Note that it will not convert padding specifications,
        !            11: so they must be done by hand.  Note also that typical termcap entries
        !            12: do not give as much information as terminfo, so the resulting terminfo
        !            13: entry is often incomplete (e.g. won't tell you the terminal uses
        !            14: xon/xoff handshaking, or what extra function keys send).  You are
        !            15: urged to read the list of terminfo capabilities and augment your
        !            16: terminfo descriptions accordingly.
        !            17: 
        !            18: The cvt.h file is useful for a quick hack at converting termcap programs
        !            19: which use uppercase 2 letter names for capabilities to use terminfo.
        !            20: Since tget* are provided anyway, this is of questionable value unless
        !            21: your program barely fits on a pdp-11.
        !            22: 
        !            23: The cvt.sed script is useful for actually editing the source of the same
        !            24: class of programs.  It requires a sed that understands \< and \>, the
        !            25: mod is trivial to make if you look at the corresponding code in ex or
        !            26: grep.
        !            27: 
        !            28: There are other incompatibilities at the user level between termcap and
        !            29: terminfo.  A program which creates a termcap description and then
        !            30: passes it to tgetent (e.g. vi used to do this if no TERM was set) or
        !            31: which puts such a description in the environment for a child cannot
        !            32: possibly work, since terminfo puts the parser into the compiler, not
        !            33: the user program.  If you want to give a child a smaller window, set
        !            34: up the LINES and COLUMNS environment variables or implement the JWINSIZE
        !            35: ioctl.
        !            36: 
        !            37: If you want to edit your own personal terminfo descriptions (and are not
        !            38: a super user on your system) the method is different.  Set
        !            39: TERMINFO=$HOME/terminfo (or wherever you put the compiled tree) in your
        !            40: environment, then compile your source with tic.  Tic and user programs
        !            41: will check in $TERMINFO before looking in /usr/lib/terminfo.
