=head1 NAME

pfcat - grep out function definitions from perlfunc 


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>.)


    $ 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

    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
