# A FileProxy is a proxy for a File object. It is used to prevent a File
# object from being created until it is actually necessary.
#
# For example, a site with a few thousand pages would fail to compile
# because the massive amount of file descriptors necessary, but the file
# proxy will make sure the File object is not created until it is used.

# Creates a new file proxy for the given path. This is similar to
# creating a File object with the same path, except that the File object
# will not be created until it is accessed.

# be created right before the method call takes place and destroyed
