- /* This file contains functions which simulate the termcap functions.
- *
- * It doesn't access a "termcap" file. Instead, it uses an initialized array
- * of strings to store the entries. Any string that doesn't start with a ':'
- * is taken to be the name of a type of terminal. Any string that does start
- * with a ':' is interpretted as the list of fields describing all of the
- * terminal types that precede it.
- *
- * Note: since these are C strings, you can't use special sequences like
- * ^M or \E in the fields; your C compiler won't understand them. Also,
- * at run time there is no way to tell the difference between ':' and '\072'
- * so I sure hope your terminal definition doesn't require a ':' character.
- *
- * getenv(TERM) on VMS checks the SET TERM device setting. To implement
- * non-standard terminals set the logical ELVIS_TERM in VMS. (jdc)
- *
- * Other possible terminal types are...
- * TERM_WYSE925 - "wyse925", a Wyse 50 terminal emulating Televideo 925
- * ... or you could set $TERMCAP to the terminal's description string, which
- * $TERM set up to match it.
- *
- * Note that you can include several terminal types at the same time. Elvis
- * chooses which entry to use at runtime, based primarily on the value of $TERM.
