When installing TFC for development purposes by using c='dev'; in the one-liner, the TFC-LR launcher will give the following error on all three terminals:

/bin/bash: line 0: cd: /opt/tfc/: No such file or directory

This is because the installer clones the repository to $HOME/tfc/ but the Terminator config file used is the one for local testing configuration, and so Terminator looks for TFC in /opt/tfc. This issue will be fixed in the next release. Until then, it can be fixed by running

$ sed -i 's/\/opt/\$HOME/g' $HOME/.config/terminator/config

after the installation finishes.
