# The list of file directories to publish. The first component of the tuple is
# the local path. The second component is the relative path from the server
# root. None indicates that the files will be published in the server root.
#
# The hierarchy of each directory is recreated at the relative server path.
# For example, given the local files
#
#     foo/bar/a.txt
#     foo/bar/b.txt
#
# ('foo', 'baz') would create the following files on the server:
#
#     baz/bar/a.txt
#     baz/bar/b.txt
#
# Files with the '.markdown' extension will be passed to Pandoc along with
# template files returned by the get_pandoc_template function (see the Xac class
# documentation).
#
# Non-markdown files can be interpolated using a custom get_var_delimiters
# function. This function accepts a path and returns either None or a tuple
# of variable delimiters. If it returns None for a given path, that file is
# just symlinked into the server. If it returns a tuple of delimiters, then
# the file is parsed and all configuration variables in config_vars will be
# interpolated if they are flanked by the delimiters.
#
# This will hopefully be made clear with an example. The default
# get_var_delimiters function returns ('@@@','@@@') for all files with a ".css"
# extension. When Xac publishes a CSS file, it therefore checks the file for
# "@@@foo@@@", where foo is any variable in the config_vars dictionary. All
# instances of "@@@foo@@@" are replaced by the value for foo in the dictionary.
# This enables CSS files to be easily customized using variables, but it could
# be used for any file.
