X.SH NAME
Xtcm \- merge termcap files
X.SH SYNOPSIS
X.B tcm
X[
X.B \-ns
X]
X[
X.I output-file
X]
X.I filename
X\&.\|.\|.
X.SH VERSION
XVersion 1.0, alpha release
X.SH DESCRIPTION
X.LP
X.B tcm
Xmakes an attempt at rationally combining termcap files, while also
Xdoing some consistency checking and preserving the relative ordering
Xof the entries in the files.
XFor each
X.I filename
Xgiven,
X.B tcm
Xreads the termcap entries from that file, doing many consistency
Xchecks, noting the termcap's body and whether it is unique, and
Xalso noting the names for the termcap and whether they are unique.
XOne should note that, because the files are processed in left to
Xright order, the termcaps in the files listed first have a higher
Xpriority than the termcaps listed in the files listed last, even
Xthoug an attempt is made to preserve their relative ordering.
X.PP
XWhen a termcap is read that is unique, and all of its names are
Xunique, these are all stored away for later use.
X.PP
XWhen a termcap is read that is unique, and some of its names are
Xnot unique, the user is prompted to change, delete, or ignore this
Xname, unless the "smart" mode option is used.
X.PP
XWhen a termcap is read that is not unique, and if it has names that
Xare not known, these names are added to the names of the termcap
Xthat has already been saved, and this termcap is discarded.
X.PP
XAfter all termcap entries from all of the named files are read, the
Xinternal database is traversed in order, the termcaps that have been
Xchanged are modified, and are output to
X.I output-file.
X.PP
XWhen
X.B tcm
Xchanges a termcap entry, it will prepend a comment to the body of the
Xtermcap of the form:
X.PP
X.nf
X#
X# @@tcm@@: termcap was known as "foo|bar|baz"
X#
X.fi
X.PP
XThis indicates that the termcap, when read, was known by these names,
Xbut has since changed.
X.SH OPTIONS
X.TP 15
X.BI -n
XDo not generate any output; used when checking consistency.
X.TP
X.BI -s
X"Smart" mode. When a termcap name has already been seen
Xin conjunction with another termcap, don't ask to change
Xor delete it, simply ignore it. This is perhaps the perferred
Xmode of operation, since there are many name collisions in
Xcurrent termcap files, unfortunately.
X.SH EXAMPLES
X.B tcm
Xcan be used in many ways. For these examples, assume that the file
X.I foo
Xcontains some new termcap entries you wish to add to your system
Xtermcap file,
X.I /etc/termcap.
X.PP
XFirst,
X.I tcm
Xcan be used to check the consistency of /etc/termcap by simply
Xissuing the command
X.PP
X.B tcm -ns /etc/termcap
X.PP
XThis will tell you if there are any entries that
X.B tcm
Xdoes not understand, such as improperly continued lines or
Xbadly formatted comments.
X.PP
XTo make /etc/termcap consistent, name-wise, and to be prompted
Xfor the changes necessary, use the command
X.PP
X.B tcm termcap.fixed /etc/termcap
X.PP
XTo merge a termcap file 'foo' with /etc/termcap, for example,
Xand to use 'smart' mode, use the command
X.PP
X.B tcm -s termcap.merge foo /etc/termcap
X.SH DIAGNOSTICS
X.TP 15
X.BI "usage: %s [ -sn ] [ output-file ] file [file...]"
XArguments were used incorrectly.
X.I output-file
Xis not specified if using the
X.I -n
Xoption.
X.BI "%s exists."
X.I output-file
Xexists, and
X.B tcm
Xrefuses to overwrite it.
X.TP
X.BI "No output created."
XEither the
X.I -n
Xoption was specified or an error occurred that caused tcm
Xto turn off output, since the database output would be wrong
Xanyways.
X.TP
X.BI "Unrecognized termcap (file %s near line %d): %s"
X.B tcm
Xdid not like the format of the termcap near the specified line
Xin the named file. Typically, this is either due to an improperly
Xcontinued line just above the displayed area, or to trailing comments
Xin the named file.
X.TP
X.BI "EOF encountered."
XThe EOF character was typed when
X.B tcm
Xwas expecting input.
X.B tcm
Xexits upon such an error.
X.TP
X.BI "malloc failure in %s(%d,%d)"
XUnless there's an internal error causing
X.B tcm
Xto absorb all available memory, it's likely that more
Xis needed to do the task at hand.
X.TP
X.BI "%s(%s,%d) failure."
XAn error of this form indicates a serious internal error.
X.SH BUGS
XIt is important to note that
X.B tcm
Xdoes not do semantic checking of the termcap entries; it merely
Xlooks for really glaring problems, such as badly continued lines
Xor badly formatted comments. It is forgiving of comments inside
Xof termcaps, and it shouldn't be \- only comments before or after
Xtermcap entries are valid.
X.PP
XAlso,
X.B tcm
Xis not bright enough to realize that trailing comments in /etc/termcap
Xare okay.
