// enex-dump by Steven Frank (@stevenf) <http://stevenf.com/>
//
// This script takes an Evernote export (ENEX) file as input
// and exports each individual note as a plain-text file in the
// specified output folder.
//
// All HTML formatting and attachments are stripped out.
//
// The output files are named after the title of the note.
//
// The title of the note is also included as the first line of
// the exported file.
//
// Script will attempt to create the output folder if it doesn't exist.
//
// Configure the variables below before running. Default paths are
// relative to current directory.
//
// Invoke like so:
//
// php enex-dump.php
//
// By default, we look for an input file named "My Notes.enex",
// but you can supply an additional parameter to override this:
//
// php enex-dump.php allnotes.enex
//
