Initial commit, empty scripts

You need to start somewhere. :)
First version of Linux script, untested
Fix a glitch, bash functions cannot be empty
Skip creating RD, install to $HOME
Debugging SVN-REVISION file
Still trying to fix SVN-REVISION

This time it should be OK. The problem is that there was a commit with
the .travis.yml file, and this does not correspond to any SCN commit,
obviously.
Try the OSX build script
Refine OSX script, remove gcc specific configure options
OSX: add /usr/local/bin to PATH
OSX: specify arch for gfortran
Have one sctipt only, auto-detect OS
Try building 3.1.1 on linux
Fix empty bash functions
Fix syntax error, use sudo
Don't need to specify gfortran in configure
Try without latex
Put back latex, needed for testing vignettes
OS specific configure options
Change ownership of /opt directories

So that we can install there as user.
Add deployment to GH releases
