This is a crude form.. written quickly in 5 mins. It's not efficient and is a dirty job. If you see.. there are nested loops and if you have large input and keyword files, it might bring down the efficiency.
Code:
#! /usr/bin/perl -w
use strict;

my ( %keywords );
my ( $line, $key, $value );

open K, "< keyword.txt";
while ( $line = <K> ) {
    chomp ( $line );
    $keywords { $line } = 0;
}
close K;

open I, "< input.txt";
while ( $line = <I> ) {
    chomp ( $line );
    foreach $key ( keys %keywords ) {
        while ( $line =~ /$key/g ) {
            $keywords{ $key }++;
        }
    }
}
close I;

while ( ( $key, $value ) = each %keywords ) {
    print "$key has occured $value times.\n";
}

gtkdoc-mktmpl

gtkdoc-mktmpl(1)					      General Commands Manual						  gtkdoc-mktmpl(1)

NAME

       gtkdoc-mktmpl --  GTK DocBook documentation generator.

SYNOPSIS

       gtkdoc-mktmpl [ See below ]

DESCRIPTION

       gtkdoc-mktmpl This creates or updates the template files which contain the manually-edited documentation. (A template is a simple text form
       which is filled in with the description of a function, macro, enum, or struct.  For functions  and  macros  it  also  contains  fields  for
       describing the parameters.)

       This script reads in the existing templates, found in tmpl/*.sgml, moves these files to tmpl/*.sgml.bak, and then recreates the .sgml files
       according to the structure given in the file MODULE-sections.txt.

       Any new templates added, or new function parameters, are marked with FIXME so you can do a grep to see which parts need updating.

       Any templates which are no longer used (i.e. they are remove from MODULE-sections.txt) are placed in the  file  tmpl/MODULE-unused.txt.	If
       they are included again later they are automatically copied back into position.	If you are certain that these templates will never be used
       again you can delete them from MODULE-unused.txt.

       Any parameters to functions which are no longer used are separated from the rest of the parameters with the line <!-- # Unused Parameters #
       -->.  It  may  be  that	the parameter name has just been changed, in which case you can copy the description to the parameter with the new
       name. You can delete the unused parameter descriptions when no longer needed.

EXAMPLE

       See /usr/share/doc/gtk-doc-tools/examples, for a makefile.am and a configure.in example file.
