    e2s: simple script to import (Evernote) notes to Simplenote

    This script relies on two projects:
    - ever2simple (https://github.com/claytron/ever2simple) to covert Evernote ENEX files to JSON
    - simplenote python API (https://pypi.python.org/pypi/simplenote) used in this script to upload the notes

    Note: Simplenote expects dates in UNIX Timestamp format. I have posted a pull request for ever2simple
    to issue dates in this format, but so far the PR is still pending. In the meantime you shoudl use my fork
    (https://github.com/AmedeeBulle/ever2simple)

    Process I used to migrate from Evernote to Simplenote:
        1. Install ever2simple (my fork) and the simplenote python API (e.g. pip install simplenote)
        2. Export your Evernote notes in ENEX format. I exported notebook per notebook to be able to tag
           the notes per notebook.
           If you export all your notes in one big file, notebooks info will be lost.
        3. Using ever2simple convert ENEX files into JSON. E.g. for each file:
           ever2simple -o notebook1.json -f json -e notebook1.enex
           The '-e' option is important, it writes date in UNIX timestamp format
        4. Using this script: upload to Simplenote. E.g.:
           e2s.py -t NoteBook1 -u myuser -p mypassword  notebook1.json
           (-t is optional and allows you to add a tag to all notes)
           
    This script is rather simplistic (no error checking, ...) but worked for me to migrate from Evernote 
    to Simplenote.
    Usual disclaimers: use and enjoy at your own risks...
