The problem is we have different types of configuration in gitweb, and we
should take care where to put appropriate configuration options/variables.

- build time options, like $gitexecdir ($gitbin now) or $gitweb_version 
  ($version now) which could be set at build time a la ./configure i.e
  my $gitexecdir = "@GIT_EXEC_DIR@"; or something like that.

- gitweb installation options (gitweb version need not to correspond to 
  git version, and we could theoretically have more than one gitweb
  installation while one git-core installation). It was proposed to put
  such options on gitweb.conf file in the same directory as gitweb.cgi.
  Unfortunately if one would want to use git-repo-config for managing
  gitweb.conf one is out of luck: git-repo-config uses $GIT_DIR/config.

  Among installation options we could put also defaults for repository-wide
  (repository specific) options.

  Global gitweb options include:
  * $projectroot - absolute fs-path which will be prepended to the 
    project path, i.e. where projects to display are located (dir)
  * $projects_list - source of projects list (file)
  * $home_text - html text to include at home page (file)
  * $stylesheet - default gitweb stylesheet (file)
  * $git_temp - where to place temporary files (dir)

- repository specific options, of which gitweb for now uses only 
  $GIT_DIR/description, and which could use repository configuration,
  [gitweb] section.

  Repository specific options [can] include:
  * description - One line description of repository; 
    theoretical problem: HTML escaping.
  * blame - to make 'blame'/'annotate' interface available.
  * blobmimemapfile - for repository specific mime map for blob_plain.
  * favicon - if default favicon is not used.
