=head1 NAME
pfgrep - grep out function definitions from perlfunc
=head1 DESCRIPTION
This program uses I<podgrep> program to search your configuration's
L<perlfunc> for function definitions. It honors a B<-f> flag to
format through I<pod2text> and a B<-p> flag to send the output
through the pager. (Actually, it just passes these to I<podgrep>.)
=head1 EXAMPLES
$ pfcat seek
(find all seek functions (including sysseek))
$ pfcat -pf sprintf
(sprintf function is formated and sent to pager)
$ pfcat -f '\bint\b'
/usr/local/devperl/lib/5.00554/pod/perlfunc.pod chunk 506
int EXPR
int
Returns the integer portion of EXPR. If EXPR is omitted, uses
`$_'. You should not use this for rounding, because it truncates
towards `0', and because machine representations of floating point
numbers can sometimes produce counterintuitive results. Usually
`sprintf()' or `printf()', or the `POSIX::floor' or `POSIX::ceil'
functions, would serve you better.
You can also run this using alternate perl binaries, like so:
$ oldperl -S pfcat open
....
