Remove-DSStore.ps1

#.SYNOPSIS
# Removes all .DS_Store files from the current directory as well
# as any subdirectories.
#.DESCRIPTION
# .DS_Store is an artifact left by Mac OSX. On Mac that is harmless
# to remove, but otherwise pretty annoying. They tend to make their
# way into remote file shares and zip files and are not hidden by
# default in Windows.
