A regexp can be preceded by {lang}, thus restriciting it to match lines of
files of the specified language. Use \fBetags --help\bP to obtain a list
of the recognised languages. This feature is particularly useful inside
\fBregex files\fB. A regex file contains one regex per line. Empty lines,
and those lines beginning with space or tab are ignored. Lines beginning
with @ are references to regex files whose name follows the @ sign. Other
lines are considered regular expressions like those following \-\-regex.

For example, the command
