$L_KEYWORD
: Value of local RCS-like keywordFor 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.
