HOWTO: Make a release

Making a release from the Git HEAD:

• Clone the repo: git clone https://github.com/philpem/printer-driver-ptouch ptouch-driver-${VERSION}
• cd ptouch-driver-v${VERSION}
• Bump the version number in 'configure.ac' (AC_INIT... line)
• Make sure any new printer drivers have been put in the Makefile.am
• Commit and push the changes (don't worry about tagging, this happens in the Release stage)
• Build the configure script: ./autogen.sh
• Clean up: rm -rf .git* autom4te.cache
• cd ..
• tar zcf ptouch-driver-VERSION.tar.gz ptouch-driver-VERSION
• Create Github release from tag (https://github.com/philpem/printer-driver-ptouch/releases) and upload the tarball
• DONE!
