$L_KEYWORD: Value of local RCS-like keyword

For most purposes, $L_KEYWORD behaves as @k (see ATk). It is still under development and should not be used yet.

$L_KEYWORD("Keyword") extracts (as a character string) the text of an RCS-like keyword defined in the ignorable commentary between @z and @x at the beginning of a file included via @i. $L_KEYWORD("local keyword") is expanded during input, and the results are known only during the time the include file is being read.

Note that the argument of $L_KEYWORD must be a quoted string. For more discussion of the distinction between local and global keywords, please see ATz and $KEYWORD.

It is expected that local keywords will rarely be used, as fundamental revision-control information should presumably be extracted from the top of the master web file.
