# Installs a basic fallback Bash environment into the
# user's $HOME directory.
#
# usage: bashInstall [ --install | --check | --remove | --clean | --nuke ]
#
#        where --install: installs other development related config files
#              --check:   checks what was installed
#              --remove:  removes files which were installed
#              --clean:   same as above, deletes emptied directories
#              --nuke:    same as above but cleans up other content
#
# For more traditional Unix pre-XDG utilities.
