Emacs require project support (like in every IDE).

[Oleksandr Gavenko]

Yea, I know:

  http://search.gmane.org/?query=project&group=gmane.emacs.help
  site:emacswiki.org project
  http://stackoverflow.com/search?q=emacs+project

I try 'eproject' in one evening and get stuck in its manual. And I know that
this is external package...

I can't find build-in replace in many files command (except
tags-query-replace, which require TAGS file).

I dictate '_build'/'_dist' dir names in my job project to speedup and avoid
duplications when "M-x rgrep" (as generic name 'build' may be occurred in
source hierarchy!).

I actively use '.dir-locals.el'. Fine thing. They mostly solve:

 * per project configs (like indenting/formatting/character encoding)

but with some issues. And there are no any user friendly editing interface...

Next:

 * per project M-c compile in any project subdir
 * completion to make/ant/maven/etc build tools ('Ant' have '-p', GNU also
   make can dump all targets by '-p', ...)

'find-file-at-point' can search for .js files completion in 'src/js' dir, for
.jsp files in 'src/webapp', etc.

Also:

 * per project searches/replaces


But most wanted is a standard API and conventions to retrieve per-project
settings for current buffer or directory.

So instead of thousand incompatible external hacks from emacs wiki - one
implementation in Emacs core.
