A simple unix/linux daemon in Python

I've written a simple Python class for creating daemons on unix/linux systems. It was pieced together for various other examples, mostly corrections to various Python Cookbook articles and a couple of examples posted to the Python mailing lists. It has support for a pidfile to keep track of the process. I hope it's useful to someone.

# ag <https://github.com/ggreer/the_silver_searcher>
# usage: ag-replace.sh [search] [replace]
# caveats: will choke if either arguments contain a forward slash
# notes: will back up changed files to *.bak files

ag -0 -l $1 | xargs -0 perl -pi.bak -e "s/$1/$2/g"

# or if you prefer sed's regex syntax:

ag -0 -l $1 | xargs -0 sed -ri.bak -e "s/$1/$2/g"

// Functions from Go's strings package usable as template actions
// with text/template.
//
// This approach assumes you have some context type as a receiver,
// but if you just need the functions check out the FuncMap variant
// below.
// 
// Commented functions are not deemed useful in template actions.
// Haven't actually used this, but this is one possible way of doing it.
// Another option is to fill a FuncMap with most of the strings package.
