#   ───────────────────────── CDPATH projects dir ──────────────────────────

# For example, if you have a project at $HOME/projects/myproject,
# you can simply run 'cd myproject' from anywhere and it will take you there.
# 'cd' command prioritizes directories in CDPATH, so if you have a directory with
# the same name in both $HOME/projects and $HOME, it will take you to the one in $HOME/projects first.
# Additionally, directories inside the CWD will still take precedence over CDPATH,
# so if you have a directory named 'myproject' in the current directory,
# running 'cd myproject' will take you there instead of $HOME/projects/myproject.
