; The easiest way to use this file is to just add an acl2-customization.lsp
; file to your home directory that says:
;
; (ld "std/std-customization.lsp" :dir :system)
;
; You can, of course, put whatever additional customization you want in your
; own customization file, then.
; There's no in-package here, because it could screw up packages loaded by
; custom acl2-customization.lsp files. Instead we use the #!ACL2 syntax to try
; to make sure this file can be read from any package.
; This file is mentioned in books/doc/practices.lisp.

; XDOC SUPPORT
;
; - Always load the xdoc package, which is pretty fast.
;
; - Unless :SUPPRESS-PRELOAD-XDOC has been assigned, also get the xdoc
; database preloaded so that :XDOC commands are very fast and never
; leave any nonsense in your history.
;
; The second part is somewhat slow and makes ACL2 take noticeably longer to
; boot up. However, for me, on the par, it seems worth it to make :xdoc much
; more useful.
;
; The suppress-preload-xdoc mechanism can be used to make sure that xdoc does
; NOT get preloaded. Why would you want to do this?
;
; Well, a few libraries (e.g., str) have some files (package definitions,
; str::cat, etc.) that are included in the xdoc implementation code that gets
; loaded by (xdoc::colon-xdoc-init). When you're hacking on these libraries,
; it's very easy to, e.g., change something that causes xdoc to be completely
; unloadable until you recertify everything.
;
; At any rate, if for this (or some other reason) you don't want to
; automatically do this xdoc initialization, you can just add:
;
; (assign :suppress-preload-xdoc t)
;
; Before loading std-customization.lsp.
