iptables-save / iptables-restore fast firewall reload

I have several thousand lines long firewall generated by some perl
scripts . I am looking for a fast way to reload that firewall with

Is there any way to parse my firewall/whatever.sh into
iptables-restore (actually iptables-restore) format ?
I've found that if i have a firewall script  that has let's say "full"
syntax  (i mean to declare each table - filter,nat and mangle with
"-t" option ) it should be easy to parse it like that :

cat filter.header.txt > iptables-restore.bin
grep "-t filter" firewall.sh >> iptables-restore.bin
cat nat.header.txt >> iptables-restore.bin
grep "-t nat" firewall.sh >> iptables-restore.bin
cat mangle.header.txt >> iptables-restore.bin
grep "-t mangle" firewall.sh >> iptables-restore.bin

content of filter files is like :
:ICMP - [0:0]
:SKAN - [0:0]
:SUM - [0:0]
:WATCH - [0:0]

and so on

Is it possible ?
Do You have your own solutions ?
