# more limited than my full dotfiles - just the things I'm likely to use on
# other people's servers.
#
# It is read by 'ssh-with-bashrc' and passed via SSH, so it can't be too long.
# The maximum length of a command + environment variables is around 2MB on
# Ubuntu (according to `getconf ARG_MAX`), which should be plenty. I tried
# passing it over FD3 instead, but SSH doesn't pass additional file descriptors
# to the remote server.
#
# Comments and blank lines are removed before sending.
