rcs: ident
2.4 Invoking ident
==================
ident [options] [file ...]
If no FILE is specified, scan standard input. The ident command scans
its input for keywords (⇒Concepts), displaying to standard output
what it finds.
-q
Normally, if no patterns are found for a file, ident emits a
warning. This option suppresses the warning.
-V
Note that ‘-VN’ is _not_ a valid option for ident, in contrast to
most other RCS commands (⇒Misc common options).
In addition to the normal keyword pattern, for Subversion 1.2 (and
later) compatibility(1), ident also recognizes patterns having one of
the forms:
$KEYWORD:: TEXT $
;; two colons and space after keyword
;; space before ending $
$KEYWORD:: TEXT#$
;; two colons and space after keyword
;; hash before ending $

(1) The “fixed-length keyword syntax” is described in detail in
Version Control with Subversion, chapter “Advanced Topics”, section
“Keyword Substitution”.
