    devel.module
    macro.module

basic debug tabs added to Views pages. needs work to consider Views arguments. also needs port to D6 once Views for D6 becomes public.

#110407 add uninstall step to reinstall feature. beware, this reinstall will now delete all module data first. i added a warning to this effect.

add function and link for rebuilding node_comment_statistics table using pure SQL. also some other migration related helper functions.

move a brace down in devel_shutdown() so the ['devel_shutdown'] marker actually does soemthing. thanks Earl.

i picked wrong solution for #140417 - avoid breaking javascript/image pages with devel_shutdown() output

- Code didn't correctly handle sites where the 'Switch users'
  permission has been granted to the 'authenticated users' role.
- Queries didn't properly filter out uid 0.
- Queries were not PgSQL compliant.

should prefer to list users that are allowed to switch, and visually
mark them (via theme('placeholder')) so you know who can switch back.

once again, the query log and friends are compatible with page cache. we even output a query log even if a cached page was served. useful for assuring you are fully optimized for cached pages. no longer using javascript to output the query log ... AHAH and other pages can use ['devel_shutdown'] = FALSE to suppress devel output

rollback of ltr patch. i am not seeing devel output render on page properly with this. the section is empty
