// This script convert a log file made by cozy-desktop to a file that can be
// used with gource to visualize it.
//
// Gource: https://gource.io/
//
// To use it, first install Gource, then:
//
//     $ ./dev/log2gource.js < desktop.log > gource.log
//     $ gource --seconds-per-day 60 gource.log
//
// Gource has a pipe ('|') delimited custom log format:
//     timestamp - A unix timestamp of when the update occured.
//     username  - The name of the user who made the update.
//     type      - initial for the update type - (A)dded, (M)odified or (D)eleted.
//     file      - Path of the file updated.
//     colour    - A colour for the file in hex (FFFFFF) format. Optional.
//
// TODO we may use the red colour to highlight the conflicts
