Well, there are these quite useful things called regular expressions.

How do you tell SEARCH to search for the equivalent of

egrep '^[a-z0-9_]([a-z_0-9]*[ 	])*([a-z_0-9]+)[ 	]*\([a-z_0-9 	,]*\)[ 	]*{?[ 	]*(\/\*.*)?$' "$@"

which locates (sanely laid out) C procedure definitions?
(The r.e.s in grep would be a little different, but I had the egrep version to
hand)

(Sorry if the mailer garbles this - the spaces in the square brackets really
mean "any whitespace" which vanilla [ef]+grep doesn't support directly.)
