37906 *
37907 * A public domain implementation of the termcap(3) routines.
37908 *
37909 *
37910 *
37911 * Klamer Schutte V1.2 Nov. 1988
37912 *
37913 * - Can match multiple terminal names [tgetent]
37914 * - Removal of **area assignments [tgetstr]
37915 *
37916 * Terrence W. Holm V1.3 May, Sep, Oct. 1988
37917 *
37918 * - Correct when TERM != name and TERMCAP is defined [tgetent]
37919 * - Correct the comparison for the terminal name [tgetent]
37920 * - Correct the value of ^x escapes [tgetstr]
37921 * - Added %r to reverse row/column [tgoto]
37922 * - Fixed end of definition test [tgetnum/flag/str]
37923 *
37924 * Terrence W. Holm V1.4 Jan. 1989
37925 *
37926 * - Incorporated Klamer's V1.2 fixes into V1.3
37927 * - Added %d, (old %d is now %2) [tgoto]
37928 * - Allow '#' comments in definition file [tgetent]
