+As another example, R requires the @code{CURL_CA_BUNDLE} environment
+variable to point to a certificate bundle, so you would have to run
+something like this:
+
+@example
+$ guix package -i nss-certs
+$ export CURL_CA_BUNDLE="$HOME/.guix-profile/etc/ssl/certs/ca-certificates.crt"
+@end example
+
+For other applications you may want to look up the required environment
+variable in the relevant documentation.
