# The program_name.header must be use this structure:
#
# .TH <program_name> "<manpage_level>" "<date>" "<program_name_upper_case> <program_version>" "<program_description>"
#
# Example:
#
# .TH mac-robber "1" "May 2013" "MAC-ROBBER 1.02" "collects data about allocated files in mounted filesystems"
