-@node Initialization File Semantics
-@comment node-name, next, previous, up
-@subsection Initialization File Semantics
-
SBCL processes initialization files with @code{read} and @code{eval},
not @code{load}; hence initialization files can be used to set startup
@code{*package*} and @code{*readtable*}, and for proclaiming a global
optimization policy.
