// XPCShell script for generating a single file containing all certificates in PEM
// format. You may run this in the browser toolbox's console
// (Firefox -> devtools -> settings -> enable remote/chrome debugging,
// followed by settings -> devtools menu -> browser toolbox) or the
// xpcshell runner that comes with a built Firefox (./run-mozilla.sh ./xpcshell).
// The variable `certstring` contains the final pem file. You can use `save(path)` to
// save it to a file. `certlist` contains an array with the PEM certs as well as their names if you
// want to filter them.
