+Equal returns true iff protocol buffers a and b are equal.

+Equality is defined in this way:
+  - Two messages are equal iff they are the same type,
+    corresponding fields are equal, unknown field sets
+    are equal, and extensions sets are equal.
+  - Two set scalar fields are equal iff their values are equal.
+    If the fields are of a floating-point type, remember that
+    NaN != x for all x, including NaN. If the message is defined
+    in a proto3 .proto file, fields are not "set"; specifically,
+    zero length proto3 "bytes" fields are equal (nil == {}).
+  - Two repeated fields are equal iff their lengths are the same,
+    and their corresponding elements are equal (a "bytes" field,
+    although represented by []byte, is not a repeated field)
+  - Two unset fields are equal.
+  - Two unknown field sets are equal if their current
+    encoded state is equal.
+  - Two extension sets are equal iff they have corresponding
+    elements that are pairwise equal.
+  - Every other combination of things are not equal.

+Package proto converts data structures to and from the wire format of
+protocol buffers.  It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+  - Names are turned from camel_case to CamelCase for export.
+  - There are no methods on v to set fields; just treat
+	them as structure fields.
+  - There are getters that return a field's value if set,
+	and return the field's default value if unset.
+	The getters work even if the receiver is a nil message.
+  - The zero value for a struct is its correct initialization state.
+	All desired fields must be set before marshaling.
+  - A Reset() method will restore a protobuf struct to its zero state.
+  - Non-repeated fields are pointers to the values; nil means unset.
+	That is, optional or required field int32 f becomes F *int32.
+  - Repeated fields are slices.
+  - Helper functions are available to aid the setting of fields.
+	msg.Foo = proto.String("hello") // set field
+  - Constants are defined to hold the default values of all fields that
+	have them.  They have the form Default_StructName_FieldName.
+	Because the getter methods handle defaulted values,
+	direct use of these constants should be rare.
+  - Enums are given type names and maps from names to values.
+	Enum values are prefixed by the enclosing message's name, or by the
+	enum's type name if it is a top-level enum. Enum types have a String
+	method, and a Enum method to assist in message construction.
+  - Nested messages, groups and enums have type names prefixed with the name of
+	the surrounding message type.
+  - Extensions are given descriptor names that start with E_,
+	followed by an underscore-delimited list of the nested messages
+	that contain it (if any) followed by the CamelCased name of the
+	extension field itself.  HasExtension, ClearExtension, GetExtension
+	and SetExtension are functions for manipulating extensions.
+  - Oneof field sets are given a single field in their message,
+	with distinguished wrapper types for each possible field value.
+  - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+  - Non-repeated fields of non-message type are values instead of pointers.
+  - Getters are only generated for message and oneof fields.
+  - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.

-sqlx is a library which provides a set of extensions on go's standard
-`database/sql` library.  The sqlx versions of `sql.DB`, `sql.TX`, `sql.Stmt`,
-et al. all leave the underlying interfaces untouched, so that their interfaces
-are a superset on the standard ones.  This makes it relatively painless to
-integrate existing codebases using database/sql with sqlx.

-Major additional concepts are:
-
-* Marshal rows into structs (with embedded struct support), maps, and slices
-* Named parameter support including prepared statements
-* `Get` and `Select` to go quickly from query to struct/slice
-
-In addition to the [godoc API documentation](http://godoc.org/github.com/jmoiron/sqlx),
-there is also some [standard documentation](http://jmoiron.github.io/sqlx/) that
-explains how to use `database/sql` along with sqlx.
-
-## Recent Changes
-
-* sqlx/types.JsonText has been renamed to JSONText to follow Go naming conventions.
-
-This breaks backwards compatibility, but it's in a way that is trivially fixable
-(`s/JsonText/JSONText/g`).  The `types` package is both experimental and not in
-active development currently.
-
-More importantly, [golang bug #13905](https://github.com/golang/go/issues/13905)
-makes `types.JSONText` and `types.GzippedText` _potentially unsafe_, **especially**
-when used with common auto-scan sqlx idioms like `Select` and `Get`.
-
-### Backwards Compatibility
-
-There is no Go1-like promise of absolute stability, but I take the issue seriously
-and will maintain the library in a compatible state unless vital bugs prevent me 
-from doing so.  Since [#59](https://github.com/jmoiron/sqlx/issues/59) and 
-[#60](https://github.com/jmoiron/sqlx/issues/60) necessitated breaking behavior, 
-a wider API cleanup was done at the time of fixing.  It's possible this will happen
-in future;  if it does, a git tag will be provided for users requiring the old
-behavior to continue to use it until such a time as they can migrate.
-
-## install
-
-    go get github.com/jmoiron/sqlx
-
-## issues
-
-Row headers can be ambiguous (`SELECT 1 AS a, 2 AS a`), and the result of
-`Columns()` does not fully qualify column names in queries like:
-
-```sql
-SELECT a.id, a.name, b.id, b.name FROM foos AS a JOIN foos AS b ON a.parent = b.id;
-```
-
-making a struct or map destination ambiguous.  Use `AS` in your queries
-to give columns distinct names, `rows.Scan` to scan them manually, or 
-`SliceScan` to get a slice of results.
-
-## usage
-
-Below is an example which shows some common use cases for sqlx.  Check 
-[sqlx_test.go](https://github.com/jmoiron/sqlx/blob/master/sqlx_test.go) for more
-usage.

-# reflectx
-
-The sqlx package has special reflect needs.  In particular, it needs to:
-
-* be able to map a name to a field
-* understand embedded structs
-* understand mapping names to fields by a particular tag
-* user specified name -> field mapping functions
-
-These behaviors mimic the behaviors by the standard library marshallers and also the
-behavior of standard Go accessors.
-
-The first two are amply taken care of by `Reflect.Value.FieldByName`, and the third is
-addressed by `Reflect.Value.FieldByNameFunc`, but these don't quite understand struct
-tags in the ways that are vital to most marshalers, and they are slow.
-
-This reflectx package extends reflect to achieve these goals.

-Description
------------
-
-sqlite3 driver conforming to the built-in database/sql interface
-
-Installation
-------------
-
-This package can be installed with the go get command:
-
-    go get github.com/mattn/go-sqlite3
-    
-_go-sqlite3_ is *cgo* package.
-If you want to build your app using go-sqlite3, you need gcc.
-However, if you install _go-sqlite3_ with `go install github.com/mattn/go-sqlite3`, you don't need gcc to build your app anymore.
-    
-Documentation
--------------
-
-API documentation can be found here: http://godoc.org/github.com/mattn/go-sqlite3
-
-Examples can be found under the `./_example` directory
-
-FAQ
----
-
-* Want to build go-sqlite3 with libsqlite3 on my linux.
-
-    Use `go build --tags "libsqlite3 linux"`
-
-* Want to build go-sqlite3 with libsqlite3 on OS X.
-
-    Install sqlite3 from homebrew: `brew install sqlite3`
-
-    Use `go build --tags "libsqlite3 darwin"`
-
-* Want to build go-sqlite3 with icu extension.
-
-   Use `go build --tags "icu"`
-
-* Can't build go-sqlite3 on windows 64bit.
-
-    > Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit. 
-    > See: https://github.com/mattn/go-sqlite3/issues/27
-
-* Getting insert error while query is opened.
-
-    > You can pass some arguments into the connection string, for example, a URI.
-    > See: https://github.com/mattn/go-sqlite3/issues/39
-
-* Do you want to cross compile? mingw on Linux or Mac?
-
-    > See: https://github.com/mattn/go-sqlite3/issues/106
-    > See also: http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html
-
-* Want to get time.Time with current locale
-
-    Use `loc=auto` in SQLite3 filename schema like `file:foo.db?loc=auto`.

-Package sqlite3 provides interface to SQLite3 databases.
-
-This works as a driver for database/sql.
-
-Installation
-
-    go get github.com/mattn/go-sqlite3
-
-Supported Types
-
-Currently, go-sqlite3 supports the following data types.
-
-    +------------------------------+
-    |go        | sqlite3           |
-    |----------|-------------------|
-    |nil       | null              |

-SQLite3 Extension
-
-You can write your own extension module for sqlite3. For example, below is an
-extension for a Regexp matcher operation.
-
-    #include <pcre.h>
-    #include <string.h>
-    #include <stdio.h>
-    #include <sqlite3ext.h>
-
-    SQLITE_EXTENSION_INIT1
-    static void regexp_func(sqlite3_context *context, int argc, sqlite3_value **argv) {
-      if (argc >= 2) {
-        const char *target  = (const char *)sqlite3_value_text(argv[1]);
-        const char *pattern = (const char *)sqlite3_value_text(argv[0]);
-        const char* errstr = NULL;
-        int erroff = 0;
-        int vec[500];
-        int n, rc;
-        pcre* re = pcre_compile(pattern, 0, &errstr, &erroff, NULL);
-        rc = pcre_exec(re, NULL, target, strlen(target), 0, 0, vec, 500);
-        if (rc <= 0) {
-          sqlite3_result_error(context, errstr, 0);
-          return;
-        }
-        sqlite3_result_int(context, 1);
-      }
-    }
-
-    #ifdef _WIN32
-    __declspec(dllexport)
-    #endif
-    int sqlite3_extension_init(sqlite3 *db, char **errmsg,
-          const sqlite3_api_routines *api) {
-      SQLITE_EXTENSION_INIT2(api);
-      return sqlite3_create_function(db, "regexp", 2, SQLITE_UTF8,
-          (void*)db, regexp_func, NULL, NULL);
-    }
-
-It needs to be built as a so/dll shared library. And you need to register
-the extension module like below.
-
-	sql.Register("sqlite3_with_extensions",
-		&sqlite3.SQLiteDriver{
-			Extensions: []string{
-				"sqlite3_mod_regexp",
-			},
-		})
-
-Then, you can use this extension.
-
-	rows, err := db.Query("select text from mytable where name regexp '^golang'")
-
-Connection Hook
-
-You can hook and inject your code when the connection is established. database/sql
-doesn't provide a way to get native go-sqlite3 interfaces. So if you want,
-you need to set ConnectHook and get the SQLiteConn.
-
-	sql.Register("sqlite3_with_hook_example",
-			&sqlite3.SQLiteDriver{
-					ConnectHook: func(conn *sqlite3.SQLiteConn) error {
-						sqlite3conn = append(sqlite3conn, conn)
-						return nil
-					},
-			})
-
-Go SQlite3 Extensions
-
-If you want to register Go functions as SQLite extension functions,
-call RegisterFunction from ConnectHook.
-
-	regex = func(re, s string) (bool, error) {
-		return regexp.MatchString(re, s)
-	}
-	sql.Register("sqlite3_with_go_func",
-			&sqlite3.SQLiteDriver{
-					ConnectHook: func(conn *sqlite3.SQLiteConn) error {
-						return conn.RegisterFunc("regexp", regex, true)
-					},
-			})
-
-See the documentation of RegisterFunc for more details.
