Привет всем! Помогите конвертировать .htaccess в файл .conf для nginx.

Содержание .htaccess:

RewriteEngine On
Options -Indexes
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php

RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L]

RewriteRule ^([0-9a-zA-Z-_-]+)$ user.php?seller_user_name=$1

RewriteCond %{HTTP_HOST} !=localhost
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule (.*) https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

#Now, rewrite to HTTPS if www present:
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !=localhost
RewriteCond %{HTTP_HOST} ^www\.
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Заранее благодарен.
