# This file converts a coverate data file, produced by the simple coverage
# package, into an html file showing the covered and uncovered parts of the 
# code.
#
# The format of the simple coverage package data is
#  routine \t nargs \t #calls \t sourcefile \t first-line \t last-line \n
# sorted by routine name and number of arguments.
#
# NOT YET WRITTEN
# This program reads the data file; then takes each different source file
# and creates a simple HTML version, using color to accent uncovered and
# covered code
#
# First step:
#    read file.  Save data as
#    %SourceFiles{ name } => internal hash name
#    %internalhashname{ firstline } => "lastline:routine:argcount:ncall"
#
# Then we can sort on the keys and the use that for "next line with covered"
#
# Reading the source code, we check each
#     COVERAGE_BEGIN/END
# for a corresponding entry in the data (in internalhashname).  Surround
# the block with pale green or red if covered or uncovered.
#
