# Process for securely uploading files to Sourceforge, taken from
# https://oncletom.io/2016/travis-ssh-deploy/:
#
# Contact chrisdembia if you need the login information for opensim-bot at
# sourceforge, to manage myosin.sourceforge.net.
#
# You must install the travis command-line tool: `gem install travis`
# Locally, from the root of the simbody repository:
# Create a 4096-bit RSA key with comment, private key 
# $ ssh-keygen -t rsa -b 4096 -C 'opensim-bot@sourceforge.net' -f doc/.deploy_myosin_sourceforge_rsa
# When prompted for a passphrase, just hit enter (twice).
# Encrypt the private key, add decryption code to .travis.yml. First make a
# backup copy of .travis.yml.
# $ travis encrypt-file doc/.deploy_myosin_sourceforge_rsa --add
# Manually edit the .travis.yml file to clean up the added lines and restore
# comments to the file; put the decryption in the before_deploy step.
# Remove the unencrypted private key. DO NOT commmit the unencrypted private
# key.
# $ rm -f doc/.deploy_myosin_sourceforge_rsa
# Move the encrypted key to the doc folder.
# $ mv .deploy_myosin_sourceforge_rsa.enc doc/
# Manually, log into the sourceforge website (user opensim-bot) and add the
# public key (contents of doc/.deploy_myosin_sourceforge_rsa.pub) in
# Profile > SSH Settings.
# Now you can delete the public key file from your local machine.
# Commit the encrypted private key and the changes to .travis.yml.
# $ git commit .travis.yml doc/.deploy_myosin_sourceforge_rsa.enc
