# sbcl(1), FILES: the system init file is "sbclrc" in $SBCL_HOME and then /etc,

# "unless overridden by the --sysinit command line option", and the user init

# file is ".sbclrc" in "the user's home directory, or as specified by

# --userinit". The manual lists the same set — $SBCL_HOME/sbclrc, /etc/sbclrc,

# $HOME/.sbclrc, ~/.sbclrc — and only the last is per user. On Windows the home

# spelling is %USERPROFILE%\.sbclrc, which resolves to the same path as

# ~/.sbclrc.

# Read once when an image starts and not held open afterwards, so rewriting it

# No machine_lines: an .sbclrc is require forms, reader tweaks and debugger

# settings, which is what a user wants everywhere. The Quicklisp block it

# usually starts with names a path under the home directory, so it is the same

# string on every machine.
