$TAG In order to use programs installed by GiteaPC, you will need to add their
$TAG install folder to your PATH. This can be done automatically when you log
$TAG in by adding the following command to your startup file:
$TAG
$TAG   export PATH="\$PATH:$PREFIX/bin"
$TAG
$TAG -> Press Enter to add this command to $default, or
$TAG -> Type another file name to add this command to, or
$TAG -> Type "-" to skip setting the PATH entirely.
