#
# This script imports iOverlander data into a imag-wiki
#
# Requirements
# ============
#
# * imag-wiki
# * imag-gps
# * imag-store
# * jq
#
# Usage
# =====
#
# Download the JSON data files from app.ioverlander.com and run them through
# this script.
#
#   ./this/script wiki-name ioverlander-file.json
#
# What it does
# ============
#
# It imports each location from the JSON data into one entry at:
#
#       <wiki_name>/<country>/<location name>_<location id>
#
# (The location id is added because names are sometimes reused)
#
# * It uses imag-gps to set the GPS data
# * It sets the header of the entry to the data it finds from the JSON object.
#   It puts all data in the "userdata.ioverlander" namespace.
#   It strips whitespace from the keys.
#   It ignores the GPS data from the JSON object though, as this was added via
#   imag-gps.
# * It uses the "description" field as entry content.
#
# Warning
# =======
#
# As the ioverlander data sometimes contains "/" in the name, some entries are
# namespaced. This has to be fixed and the linkings have to be adapted. This is
# not yet handled by this script.
