# README
The MongoDB driver for Go
Please go to http://labix.org/mgo for all project details.
Testing
Tests require custom orchestration. Install daemontools as a prerequisite and make sure mongod and mongos are in your path. To start the orchestration:
$ export PATH=/path/to/mongodb/bin:$PATH
$ make startdb
To stop the orchestration:
$ make stopdb
Run all tests like this (gocheck.v turns on verbose output):
$ go test -gocheck.v
To run a specific test, use the gocheck.f flag:
$ go test -gocheck.v -gocheck.f TestFindAndModifyBug997828
# Packages
Package bson is an implementation of the BSON specification for Go:
http://bsonspec.org
It was created as part of the mgo MongoDB driver for Go, but is standalone and may be used on its own without the driver.

The txn package implements support for multi-document transactions.
# Functions
Dial establishes a new session to the cluster identified by the given seed server(s).
DialWithInfo establishes a new session to the cluster identified by info.
DialWithTimeout works like Dial, but uses timeout as the amount of time to wait for a server to respond when first connecting and also on follow up operations in the session.

IsDup returns whether err informs of a duplicate key error because a primary key index or a secondary unique index already has an entry with the given value.
