""" An example of a Linux daemon written in Python.
Based on http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/
The changes are:
1 - Uses file open context managers instead of calls to file().
2 - Forces stdin to /dev/null. stdout and stderr go to log files.
3 - Uses print instead of sys.stdout.write prior to pointing stdout to the log file.
4 - Omits try/excepts if they only wrap one error message w/ another.

`go get` replacement that works around Go issue #5375 (go get doesn't work with private Bitbucket repositories)
#!/bin/bash
#
# Due to a bug in Go, you can't `go get` a private Bitbucket repository
# (issue #5375, linked below). This means you can't `go get ./...` ANY project
# that might depend on a private Bitbucket repository.
#
# This script works around it by detecting Bitbucket imports and using
# `git` directly to clone into it. This will not work if you use private
# Mercurial repositories on Bitbucket.
