”Generic manual inxi install method (all distros)

Simply install the script directly, like so (ArchLinux and Pardus users, change /usr/local/bin to /usr/bin):
# get it (it actually comes from code.google.com, but this is a shortcut)

cd /usr/local/bin && wget -Nc smxi.org/inxi && chmod +x inxi && inxi
