# Creates Lkmake/Simplenote import-compatible json given plaintext file of notes separated by two blank lines

# Author:  Christopher Galtenberg
# License: Use it for good, however you like

# Input file:

# example note 1
#
# example note 2

# Output file:

# [{"createdate":"Aug 01 2014 00:00:01","modifydate":"Aug 01 2014 00:00:00","content":"example 1"},{"createdate":"Aug 01 2014 00:00:02","modifydate":"Aug 01 2014 00:00:00","content":"example 2"}]

# Note: Lkmake requires non-conflicting createdate. Hence a time counter that increments createdate by 1 second for each note.
