Well just offhand, source is divided into make files, include files, library code, application (main) code, scripts including environment files, and for an O/S, kernel code. Documentation might be in scope, too. There might be other resources that need to be in place, not code or scripts but databases like time zones, terminals.

plack::app::urlmap
Plack::App::URLMap(3pm) User Contributed Perl Documentation Plack::App::URLMap(3pm)
NAME
Plack::App::URLMap - Map multiple apps in different paths
SYNOPSIS
use Plack::App::URLMap;
my $app1 = sub { ... };
my $app2 = sub { ... };
my $app3 = sub { ... };
my $urlmap = Plack::App::URLMap->new;
$urlmap->map("/" => $app1);
$urlmap->map("/foo" => $app2);
$urlmap->map("http://bar.example.com/" => $app3);
my $app = $urlmap->to_app;
DESCRIPTION
Plack::App::URLMap is a PSGI application that can dispatch multiple applications based on URL path and hostnames (a.k.a "virtual hosting")
and takes care of rewriting "SCRIPT_NAME" and "PATH_INFO" (See "HOW THIS WORKS" for details). This module is inspired by Rack::URLMap.
METHODS
map
$urlmap->map("/foo" => $app);
$urlmap->map("http://bar.example.com/" => $another_app);
Maps URL path or an absolute URL to a PSGI application. The match order is sorted by host name length and then path length.
URL paths need to match from the beginning and should match completely till the path separator (or the end of the path). For example,
if you register the path "/foo", it will match with the request "/foo", "/foo/" or "/foo/bar" but it won't match with "/foox".
Mapping URL with host names is also possible, and in that case the URL mapping works like a virtual host.
Mappings will nest. If $app is already mapped to "/baz" it will match a request for "/foo/baz" but not "/foo". See "HOW THIS WORKS"
for more details.
mount
Alias for "map".
to_app
my $handler = $urlmap->to_app;
Returns the PSGI application code reference. Note that the Plack::App::URLMap object is callable (by overloading the code dereference),
so returning the object itself as a PSGI application should also work.
DEBUGGING
You can set the environment variable "PLACK_URLMAP_DEBUG" to see how this application matches with the incoming request host names and
paths.
HOW THIS WORKS
This application works by fixing "SCRIPT_NAME" and "PATH_INFO" before dispatching the incoming request to the relocated applications.
Say you have a Wiki application that takes "/index" and "/page/*" and makes a PSGI application $wiki_app out of it, using one of supported
web frameworks, you can put the whole application under "/wiki" by:
# MyWikiApp looks at PATH_INFO and handles /index and /page/*
my $wiki_app = sub { MyWikiApp->run(@_) };
use Plack::App::URLMap;
my $app = Plack::App::URLMap->new;
$app->mount("/wiki" => $wiki_app);
When a request comes in with "PATH_INFO" set to "/wiki/page/foo", the URLMap application $app strips the "/wiki" part from "PATH_INFO" and
appends that to "SCRIPT_NAME".
That way, if the $app is mounted under the root (i.e. "SCRIPT_NAME" is "") with standalone web servers like Starman, "SCRIPT_NAME" is now
locally set to "/wiki" and "PATH_INFO" is changed to "/page/foo" when $wiki_app gets called.
