"Wrapper for loading templates from storage of some sort (e.g. files or db)"
# Wrapper for loading templates from storage of some sort (e.g. filesystem, database).
#
# This uses the TEMPLATE_LOADERS setting, which is a list of loaders to use.
# Each loader is expected to have this interface:
#
# callable(name, dirs=[])
#
# name is the template name.
# dirs is an optional list of directories to search instead of TEMPLATE_DIRS.
#
# Each loader should have an "is_usable" attribute set. This is a boolean that
# specifies whether the loader can be used in this Python installation. Each
# loader is responsible for setting this when it's initialized.
#
# For example, the eggs loader (which is capable of loading templates from
# Python eggs) sets is_usable to False if the "pkg_resources" module isn't
# installed, because pkg_resources is necessary to read eggs.
