+[OPTIONAL STEP] Merge multiple XML files
+Sometimes, having per station granularity is too accurate. If you need to merge
+two or more XML files, you can use the eccc_merge.sh script:
+
+ $ ./eccc_merger.sh "${ECCC_CACHE}/almanac/3050519.xml" \
+ "${ECCC_CACHE}/almanac/3050520.xml" "${ECCC_CACHE}/almanac/3050521.xml" \
+ "${ECCC_CACHE}/almanac/3050522.xml" "${ECCC_CACHE}/almanac/3050526.xml" \
+ > banff.xml
+
+In order to get stations ids based on their geographical position, you can use
+the eccc_map tool. A public instance is hosted online at
+https://stations.wikimedia.ca/ .
