## If your cran mirror is not in the root of your domain, e.g. yourdomain.com/CRAN/,
## then you would need to define two additional variables in your apache configuration.
## You can do it as follows
## Define CRAN_RewriteBase "/CRAN subpath on your domain/"
## Define CRAN_SystemPath "/filepath/"
## e.g.
## Define CRAN_RewriteBase "/CRAN/"
## Define CRAN_SystemPath "/var/www/CRAN/"
## !Note slashes on both sides.
