#
#    Generates an ASCII and Excel-importable file of tables representing
#    the output of running the "pio_perf" command. The name of the input
#    file is important. The name should reflect the command-line options
#    used in the performance test. It needs to be of the form:
#
#        f#[GMK].i#.d#.X#[GMK].x#[GMK]..*
#
#    For example:
#
#        PIO_output_f1G.i2.d1.X2M.x128K.frost
#
#    for a 1GB sized file ran for 2 iterations with 1 dataset from xfer
#    buffer size of 128KB to 2MB on the frost machine.
#
#    The output file will have the same name as the input, but will append
#    ".ascii" for the ASCII file and ".excel" for the Excel-importable
#    file.
#
#    The data structure used in this program looks like:
#
#        %results = {
#            num_proc => (
#                %xfer_size => (
#                    %posix = {
#                        'write-only' => ##,
#                        'write-close' => ##,

#                        'read-close' => ##
#                    },

#                        'write-only' => ##,
