Just for fun ( with the original requirements "3 lines" ) ....

Code:
# cat gen.pl
#!/usr/bin/perl

use strict;

my $meta=shift;
my $dat=shift;
my $destination=shift;

open (META,"<",$meta ) || die "cant't open file $meta \n";

my (%metadata,@line);
while (<META>) {
   /^(\d+),(\S+)\s+(\S),(\S+)\s+(\S)/;
   $metadata{$1.$2.$3} = $4.":".$5;
   }
close(META);


open (DAT,"<",$dat ) || die "cant't open file $dat \n";
open (DEST,">",$destination ) || die "cant't open file $destination \n";

while (<DAT>) {
   /^\S+\s+(\S+)\s+(\S)\S+\s+\S+\s+\S+\s+\S+$/;
   if ($1 && $2 ) { 
      $line[0]=$_;
      my ($tCode,$sig)=($1,$2);
      $_=<DAT>;
      $line[1]=$_;
      /\s+\S+(\d{4})\S+\s+.*$/;
      if ( $1) {
         my $bCode=$1;
         if ($metadata{$bCode.$tCode.$sig}) {
            $metadata{$bCode.$tCode.$sig}=~/(\S+):(\S)/;
            my ($newTcode,$newSig)=($1,$2);
            $_=$line[0];
            s/^(\S+\s+)(\S+)(\s+)(\S)(\S+\s+\S+\s+\S+\s+\S+)$/\1$newTcode\3$newSig\5/;
            print DEST;
            print DEST $line[1];
            $_=<DAT>;
            print DEST ;
            }
         else {
            print DEST $line[0].$line[1];
            $_=<DAT>;
            print DEST;

install

INSTALL(1)							   User Commands							INSTALL(1)

NAME

       install - copy files and set attributes

SYNOPSIS

       install [OPTION]... [-T] SOURCE DEST
       install [OPTION]... SOURCE... DIRECTORY
       install [OPTION]... -t DIRECTORY SOURCE...
       install [OPTION]... -d DIRECTORY...

DESCRIPTION

       This  install  program  copies  files  (often  just compiled) into destination locations you choose.  If you want to download and install a
       ready-to-use package on a GNU/Linux system, you should instead be using a package manager like yum(1) or apt-get(1).

       In the first three forms, copy SOURCE to DEST or multiple  SOURCE(s)  to  the  existing	DIRECTORY,  while  setting  permission	modes  and
       owner/group.  In the 4th form, create all components of the given DIRECTORY(ies).

       Mandatory arguments to long options are mandatory for short options too.

       --backup[=CONTROL]
	      make a backup of each existing destination file

       -b     like --backup but does not accept an argument

       -c     (ignored)

       -C, --compare
	      compare each pair of source and destination files, and in some cases, do not modify the destination at all

       -d, --directory
	      treat all arguments as directory names; create all components of the specified directories

       -D     create all leading components of DEST except the last, or all components of --target-directory, then copy SOURCE to DEST

       -g, --group=GROUP
	      set group ownership, instead of process' current group

       -m, --mode=MODE
	      set permission mode (as in chmod), instead of rwxr-xr-x

       -o, --owner=OWNER
	      set ownership (super-user only)

       -p, --preserve-timestamps
	      apply access/modification times of SOURCE files to corresponding destination files

       -s, --strip
	      strip symbol tables

       --strip-program=PROGRAM
	      program used to strip binaries

       -S, --suffix=SUFFIX
	      override the usual backup suffix

       -t, --target-directory=DIRECTORY
	      copy all SOURCE arguments into DIRECTORY

       -T, --no-target-directory
	      treat DEST as a normal file

       -v, --verbose
	      print the name of each directory as it is created

       --preserve-context
	      preserve SELinux security context

       -Z     set SELinux security context of destination file and each created directory to default type

       --context[=CTX]
	      like -Z, or if CTX is specified then set the SELinux or SMACK security context to CTX

       --help display this help and exit

       --version
	      output version information and exit

       The  backup  suffix  is '~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.  The version control method may be selected via the --backup
       option or through the VERSION_CONTROL environment variable.  Here are the values:

       none, off
	      never make backups (even if --backup is given)

       numbered, t
	      make numbered backups

       existing, nil
	      numbered if numbered backups exist, simple otherwise

       simple, never
	      always make simple backups
