How to use get_pkg:
\n-------------------
\nsh get_pkg.sh [list|install] (package name) (Target directory)
\n
\nThis script is designed to find *.so* files from within a
\ndebian $install_architecture package and copy them to a specified library
\nlocation. This over going to
\nhttps://www.debian.org/distrib/packages and then downloading
\nand extracting the librarys by hand.
\n
\n\tlist\t-
\n\t\tLists all packages matching package name
\n	
\n\tinstall\t-
\n\t\tDownloads the packages and extracts them to
\n\t\tTarget directory. (DEFAULT:$install_target)
\n\t\tYou can overrite this by specifying this after
\n\t\tspecifying the package name."
