Easy time tracking.
Keep track of time spent on projects. To start a session:
$ taevus -p project
the same command ends the session.
This will create a directory in $HOME/taevus/<project> with a log file
at $HOME/taevus/<project>/taevus_log.txt. You can view all start & end times for each
session in this file. To calculate the total # of hours worked for a project, run
$ taevus -p project --hours
'taevus' is a portmanteau of 'tempus' and 'aevum', two words in Latin that mean 'time'.
