 //
-// Go-toml can marshal and unmarshal TOML documents from and to data
+// TOML data may be parsed in two ways: by file, or by string.
-// structures.
 //
-// TOML document as a tree
+//   // load TOML data by filename
+//   tree, err := toml.LoadFile("filename.toml")
 //
-// Go-toml can operate on a TOML document as a tree. Use one of the Load*
+//   // load TOML data stored in a string
-// functions to parse TOML data and obtain a Tree instance, then one of its
+//   tree, err := toml.Load(stringContainingTomlData)
-// methods to manipulate the tree.
 //
-// JSONPath-like queries
+// Either way, the result is a TomlTree object that can be used to navigate the
+// structure and data within the original document.
 //
-// The package github.com/pelletier/go-toml/query implements a system
+//
-// similar to JSONPath to quickly retrive elements of a TOML document using a
+// Getting data from the TomlTree
-// single expression. See the package documentation for more information.
+//
+// After parsing TOML data with Load() or LoadFile(), use the Has() and Get()
+// methods on the returned TomlTree, to find your way through the document data.
+//
+//   if tree.Has("foo") {
+//     fmt.Println("foo is:", tree.Get("foo"))
+//   }
+//
+// Working with Paths
+//
+// Go-toml has support for basic dot-separated key paths on the Has(), Get(), Set()
+// and GetDefault() methods.  These are the same kind of key paths used within the
+// TOML specification for struct tames.
+//
+//   // looks for a key named 'baz', within struct 'bar', within struct 'foo'
+//   tree.Has("foo.bar.baz")
+//
+//   // returns the key at this path, if it is there
+//   tree.Get("foo.bar.baz")
+//
+// TOML allows keys to contain '.', which can cause this syntax to be problematic
+// for some documents.  In such cases, use the GetPath(), HasPath(), and SetPath(),
+// methods to explicitly define the path.  This form is also faster, since
+// it avoids having to parse the passed key for '.' delimiters.
+//
+//   // looks for a key named 'baz', within struct 'bar', within struct 'foo'
+//   tree.HasPath([]string{"foo","bar","baz"})
+//
+//   // returns the key at this path, if it is there
+//   tree.GetPath([]string{"foo","bar","baz"})
+//
+// Note that this is distinct from the heavyweight query syntax supported by
+// TomlTree.Query() and the Query() struct (see below).
+//
+// Position Support
+//
+// Each element within the TomlTree is stored with position metadata, which is
+// invaluable for providing semantic feedback to a user.  This helps in
+// situations where the TOML file parses correctly, but contains data that is
+// not correct for the application.  In such cases, an error message can be
+// generated that indicates the problem line and column number in the source
+// TOML document.
+//
+//   // load TOML data
+//   tree, _ := toml.Load("filename.toml")
+//
+//   // get an entry and report an error if it's the wrong type
+//   element := tree.Get("foo")
+//   if value, ok := element.(int64); !ok {
+//       return fmt.Errorf("%v: Element 'foo' must be an integer", tree.GetPosition("foo"))
+//   }
+//
+//   // report an error if an expected element is missing
+//   if !tree.Has("bar") {
+//      return fmt.Errorf("%v: Expected 'bar' element", tree.GetPosition(""))
+//   }
+//
+// Query Support
+//
+// The TOML query path implementation is based loosely on the JSONPath specification:
+// http://goessner.net/articles/JsonPath/
+//
+// The idea behind a query path is to allow quick access to any element, or set
+// of elements within TOML document, with a single expression.
+//
+//   result, err := tree.Query("$.foo.bar.baz")
+//
+// This is roughly equivalent to:
+//
+//   next := tree.Get("foo")
+//   if next != nil {
+//     next = next.Get("bar")
+//     if next != nil {
+//       next = next.Get("baz")
+//     }
+//   }
+//   result := next
+//
+// err is nil if any parsing exception occurs.
+//
+// If no node in the tree matches the query, result will simply contain an empty list of
+// items.
+//
+// As illustrated above, the query path is much more efficient, especially since
+// the structure of the TOML file can vary.  Rather than making assumptions about
+// a document's structure, a query allows the programmer to make structured
+// requests into the document, and get zero or more values as a result.
+//
+// The syntax of a query begins with a root token, followed by any number
+// sub-expressions:
+//
+//   $
+//                    Root of the TOML tree.  This must always come first.
+//   .name
+//                    Selects child of this node, where 'name' is a TOML key
+//                    name.
+//   ['name']
+//                    Selects child of this node, where 'name' is a string
+//                    containing a TOML key name.
+//   [index]
+//                    Selcts child array element at 'index'.
+//   ..expr
+//                    Recursively selects all children, filtered by an a union,
+//                    index, or slice expression.
+//   ..*
+//                    Recursive selection of all nodes at this point in the
+//                    tree.
+//   .*
+//                    Selects all children of the current node.
+//   [expr,expr]
+//                    Union operator - a logical 'or' grouping of two or more
+//                    sub-expressions: index, key name, or filter.
+//   [start:end:step]
+//                    Slice operator - selects array elements from start to
+//                    end-1, at the given step.  All three arguments are
+//                    optional.
+//   [?(filter)]
+//                    Named filter expression - the function 'filter' is
+//                    used to filter children at this node.
+//
+// Query Indexes And Slices
+//
+// Index expressions perform no bounds checking, and will contribute no
+// values to the result set if the provided index or index range is invalid.
+// Negative indexes represent values from the end of the array, counting backwards.
+//
+//   // select the last index of the array named 'foo'
+//   tree.Query("$.foo[-1]")
+//
+// Slice expressions are supported, by using ':' to separate a start/end index pair.
+//
+//   // select up to the first five elements in the array
+//   tree.Query("$.foo[0:5]")
+//
+// Slice expressions also allow negative indexes for the start and stop
+// arguments.
+//
+//   // select all array elements.
+//   tree.Query("$.foo[0:-1]")
+//
+// Slice expressions may have an optional stride/step parameter:
+//
+//   // select every other element
+//   tree.Query("$.foo[0:-1:2]")
+//
+// Slice start and end parameters are also optional:
+//
+//   // these are all equivalent and select all the values in the array
+//   tree.Query("$.foo[:]")
+//   tree.Query("$.foo[0:]")
+//   tree.Query("$.foo[:-1]")
+//   tree.Query("$.foo[0:-1:]")
+//   tree.Query("$.foo[::1]")
+//   tree.Query("$.foo[0::1]")
+//   tree.Query("$.foo[:-1:1]")
+//   tree.Query("$.foo[0:-1:1]")
+//
+// Query Filters
+//
+// Query filters are used within a Union [,] or single Filter [] expression.
+// A filter only allows nodes that qualify through to the next expression,
+// and/or into the result set.
+//
+//   // returns children of foo that are permitted by the 'bar' filter.
+//   tree.Query("$.foo[?(bar)]")
+//
+// There are several filters provided with the library:
+//
+//   tree
+//          Allows nodes of type TomlTree.
+//   int
+//          Allows nodes of type int64.
+//   float
+//          Allows nodes of type float64.
+//   string
+//          Allows nodes of type string.
+//   time
+//          Allows nodes of type time.Time.
+//   bool
+//          Allows nodes of type bool.
+//
+// Query Results
+//
+// An executed query returns a QueryResult object.  This contains the nodes
+// in the TOML tree that qualify the query expression.  Position information
+// is also available for each value in the set.
+//
+//   // display the results of a query
+//   results := tree.Query("$.foo.bar.baz")
+//   for idx, value := results.Values() {
+//       fmt.Println("%v: %v", results.Positions()[idx], value)
+//   }
+//
+// Compiled Queries
+//
+// Queries may be executed directly on a TomlTree object, or compiled ahead
+// of time and executed discretely.  The former is more convienent, but has the
+// penalty of having to recompile the query expression each time.
+//
+//   // basic query
+//   results := tree.Query("$.foo.bar.baz")
+//
+//   // compiled query
+//   query := toml.CompileQuery("$.foo.bar.baz")
+//   results := query.Execute(tree)
+//
+//   // run the compiled query again on a different tree
+//   moreResults := query.Execute(anotherTree)
+//
+// User Defined Query Filters
+//
+// Filter expressions may also be user defined by using the SetFilter()
+// function on the Query object.  The function must return true/false, which
+// signifies if the passed node is kept or discarded, respectively.
+//
+//   // create a query that references a user-defined filter
+//   query, _ := CompileQuery("$[?(bazOnly)]")
+//
+//   // define the filter, and assign it to the query
+//   query.SetFilter("bazOnly", func(node interface{}) bool{
+//       if tree, ok := node.(*TomlTree); ok {
+//           return tree.Has("baz")
+//       }
+//       return false  // reject all other node types
+//   })

-encoder, except that there is no concept of a Marshaler interface or MarshalTOML
-function for sub-structs, and currently only definite types can be marshaled
-(i.e. no `interface{}`).
-
-The following struct annotations are supported:
-
-  toml:"Field"      Overrides the field's name to output.
-  omitempty         When set, empty values and groups are not emitted.
-  comment:"comment" Emits a # comment on the same line. This supports new lines.
-  commented:"true"  Emits the value as commented.
-
-Note that pointers are automatically assigned the "omitempty" option, as TOML
-explicity does not handle null values (saying instead the label should be
-dropped).
-
-Tree structural types and corresponding marshal types:
-
-  *Tree                            (*)struct, (*)map[string]interface{}
-  []*Tree                          (*)[](*)struct, (*)[](*)map[string]interface{}
-  []interface{} (as interface{})   (*)[]primitive, (*)[]([]interface{})
-  interface{}                      (*)primitive
-
-Tree primitive types and corresponding marshal types:
-
-  uint64     uint, uint8-uint64, pointers to same
-  int64      int, int8-uint64, pointers to same
-  float64    float32, float64, pointers to same
-  string     string, pointers to same
-  bool       bool, pointers to same
-  time.Time  time.Time{}, pointers to same
