Translation from apache2 to nginx

Hi forumers,
I don’t know how to translate the following .htaccess to nginx rules
(from bluebox):

# Turn on URL rewriting RewriteEngine On
# Installation directory
###RewriteBase /kohana/

# If the request is for a modules assets directory allow it
RewriteRule ^modules/.*/assets/.*$ - [L]

# Protect application and system files from being viewed
###RewriteRule ^(bluebox|modules|system|upload)/ - [F,L]

# Catch requests for XML or JSON and send them through an alternate

entry point
RewriteRule ^(.+).json$ json.php/$1 [T=application/json,L]
RewriteRule ^(.+).xml$ xml.php/$1 [T=text/xml,L]

# Allow any files or directories that exist to be displayed

RewriteCond %{REQUEST_FILENAME} installer.html [OR]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# Rewrite all other URLs to index.php/URL
RewriteRule .* index.php/$0 [PT,L]

Limits the file size that a user can upload

php_value upload_max_filesize 25M

Max execution time. Is here for the media module

After X seconds, the file upload will stop

php_value max_execution_time 300
