# This is how we get the strings to be translated:
#
# 1. sed filters the tomb file and only shows the lines containing a print
#    function, e.g. warning. It outputs two columns separated by a tab.
#    The first column contains the function that is called, and the second one
#    contains the message.
#
# 2. cat adds the line number as a new first column.
#
# 3. sort orders the lines using the third column and removes contiguous 
#    duplicate lines. The third column is the string to be translated, removing
#    duplicates even if they are printed by different functions.
#
# 4. sort reorders the lines numerically using the first column.
#
# 5. awk reads the column-formatted input and outputs valid pot lines.
