# for longer explanations).
#
#   * PROMPT_COMMAND
#     E.g., PROMPT_COMMAND='echo -n "printing this prompt at " && date'
#
#   * HISTTIMEFORMAT
#     E.g., HISTTIMEFORMAT='I ran this command at: %d/%m/%y %T '
# 
#   * CDPATH
#     E.g., .:/private/work:/www
#     
#   * TMOUT
#     E.g., TMOUT=300 means log me out after 5 minutes of inactivity
#     
#   * SHLVL, LINENO, REPLY
#     You use these, rather than set them (well, 'read' sets REPLY).

# http://www.jenv.be/: Support multiple simultaneous versions of Java.
# Recommended by Dan Schultz (slifty).  TL;DR:
#   - git clone https://github.com/gcuisinier/jenv.git ~/.jenv
#   - Add ${HOME}/.jenv/bin to $PATH
#   - Put 'eval "$(jenv init -)"' in .bashrc  # i.e., as done below
#   - jenv add /usr/lib/jvm/java-8-openjdk-amd64
#   - Use 'jenv versions' to see available Java versions
#     (Examples below assume the output lists "1.8" among other things.)
#   - Use 'jenv global 1.8' to get Java 1.8 # 'local' and 'shell' work tooa
#   - Use 'java -version' to see active version
