-.SH PORTABILITY
-.PP
-X/Open Curses, Issue 7 (2009) provides a brief description of \fBtic\fP.
-It lists one option: \fB\-c\fP.
-The omission of \fB\-v\fP is unexpected.
-The change history states that the description is derived from True64 UNIX.
-According to its manual pages, that system also supported the \fB\-v\fP option.
-.PP
-Shortly after Issue 7 was released, Tru64 was discontinued.
-As of 2019, the surviving implementations of \fBtic\fP
-are SVr4 (AIX, HP-UX and Solaris),
-ncurses
-and NetBSD curses.
-The SVr4 \fBtic\fP programs all support the \fB\-v\fP option.
-The NetBSD \fBtic\fP program follows X/Open's documentation,
-omitting the \fB\-v\fP option.
-.PP
-The X/Open rationale states that some implementations of \fBtic\fP
-read terminal descriptions from the standard input if the \fIfile\fP
-parameter is omitted.
-None of these implementations do that.
-Further, it comments that some may choose to read from \*(''./terminfo.src\*(''
-but that is obsolescent behavior from SVr2,
-and is not (for example) a documented feature of SVr3.
-.SS COMPATIBILITY
-There is some evidence that historic \fB@TIC@\fR implementations treated
-description fields with no whitespace in them as additional aliases or
-short names.
-This \fB@TIC@\fR does not do that, but it does warn when
-description fields may be treated that way and check them for dangerous
-characters.
-.SS EXTENSIONS
-Unlike the SVr4 \fB@TIC@\fR command, this implementation can actually
-compile termcap sources.
-In fact, entries in terminfo and termcap syntax can
-be mixed in a single source file.
-See \fBterminfo\fR(\*n) for the list of
-termcap names taken to be equivalent to terminfo names.
-.PP
-The SVr4 manual pages are not clear on the resolution rules for \fBuse\fR
-capabilities.
-This implementation of \fB@TIC@\fR will find \fBuse\fR targets anywhere
-in the source file, or anywhere in the file tree rooted at \fBTERMINFO\fR (if
-\fBTERMINFO\fR is defined),
-or in the user's \fI$HOME/.terminfo\fR database
-(if it exists),
-or (finally) anywhere in the system's file tree of
-compiled entries.
-.PP
-The error messages from this \fB@TIC@\fR have the same format as GNU C
-error messages, and can be parsed by GNU Emacs's compile facility.
-.PP
-Aside from \fB\-c\fP and \fB\-v\fP, options are not portable:
