# 1. Make a commit if the calcurse directories contain a Git repository.
# 2. Synchronize with a CalDAV server if calcurse-caldav is configured.

# In order to install this hook, copy this file to
# $XDG_CONFIG_HOME/calcurse/hooks/ (~/.config/calcurse/hooks/) or
# ~/.calcurse/hooks/ if using ~/.calcurse.
