### set the default build directory used by other fx commands

## usage: fx set-build-dir DIR
##    or: fx --dir DIR set-build-dir
##    or: fx set-buil-dir
##
## Switches further `fx` commands to using a different build directory.
## This only works if `fx --dir DIR set ...` succeeded previously
## (and DIR has not been removed since).  The next `fx build` or other
## such command will now refer to DIR.  The previous build directory is
## left in place, so you can switch back again with `fx set-build-dir` later.
##
## fx set-build-dir without arguments will list the available build directories, naming
## the current active build directory (if any).
