+[olm] is a tool to operate on linelists provided from Global.health (G.h).
 Linelists are epidemiological datasets with information about a disease
 outbreak organised into one row per case. Currently it supports
 generating briefing reports, fetching linelists and checking linelists
 against a provided schema.
 
 olm is organised into subcommands:
 
-list        lists G.h outbreaks that olm supports
-get         saves linelist data to disk
-report      generates briefing report for an outbreak
-lint        lints (checks) an outbreak linelist for errors
