# Usage:
# 0. check your architecture
#  uname -a
# Linux laser.pe.ba.dlr.de 3.10.0-514.21.1.el7.x86_64 #1 SMP Sat Apr 22 02:41:35 EDT 2017 x86_64 x86_64 x86_64 GNU/Linux
#
# 1. search a packet for your architecture.
# Example: gnu parallel for x86_64 architecture.
# http://fr2.rpmfind.net/linux/rpm2html/search.php?query=parallel&arch=x86_64
# 
# 2. download the right file, in this case fedora 25 rpm.
# $ wget ftp://fr2.rpmfind.net/linux/fedora/linux/releases/25/Everything/x86_64/os/Packages/p/parallel-20160722-2.fc25.noarch.rpm
#
# 3. call this script
# $ ./extract_rpm.sh parallel-20160722-2.fc25.noarch.rpm
#
# this extract and a directory tree with the binary, docs, man and all.
#  
# $ tree parallel-20160722-2.fc25.noarch
