handles evaluating an attribute for a particular node
compares an attribute value to another value
a collection of attributes beyond the standard set
the standard collection of attributes available to any forester by default
takes ASTs and returns compiled TPath::Expression objects
handles the string concatenation in //@foo[1 ~ @bar ~ "quux"]
the context in which a node is evaluated during a search
a compiled TPath expression
a generator of TPath expressions for a particular class of nodes
implements the functions in expressions such as //*[:abs(@foo) = 1] and //*[:sqrt(@bar) == 2]
parses TPath expressions into ASTs
tree-specific database

handles //* expression
handles //@foo expression
handles //~foo~ expression
handles //foo expression
handles /ancestor::@foo or /preceding::@foo where this is not the first step in the path, or ancestor::@foo, etc.

role for all matching selectors
handles :root
implementation of TPath::LogStream that simply prints to STDERR
role requiring that a class have a to_string method
interface of conditional expressions in predicates
implements logical conjunction of tests
any empty role used to tag boolean TPath::Tests
role of TPath::Tests that combine multiple other tests under some boolean operator
role for tests determining whether a node has some property
TPath::Test::Node implementing attributes; e.g., //@foo
TPath::Test::Node implementing matching; e.g., //^~foo~, //^foo, and //^@foo
