need help on packaging a debian from a tar ball.

[shiv garg]

sir i am trying to package a debian from a tar ball of scilab (binary) . 
i created a folder placed every thing in right place.
and packaged it using command  dpkg -b <source > <destination>
it was packaged correctly without any warning messages or error. when i installed it using  dpkg -i <filename.deb> it was installed correctly.
when i typed command scilab, it showed that scilab pacage not installed, you can install it using sudo apt-get scilab.
when i accessed it using /usr/bin/scilab it run correctly.

i need to put the links in bin diectry..

my script file under etc/profile.d/  is

#!/bin/bash
SCILAB_PATH=/usr/scilab-5.4.1/bin
if [ -z "$PATH" ]
then
    export PATH=${SCILAB_PATH}
# check if $SCILAB_PATH is already in $PATH
elif echo $PATH | awk -F: -v j=$SCILAB_PATH '{for(i=1;i<=NF;i++){if($i == j){exit 1}}}'
then
    export PATH=${PATH}:${SCILAB_PATH}
fi
