numsum [-iIcdhrsvxy] (Input on \s-1STDIN\s0. Use Ctrl-D to stop.)
numsum will take all the numbers on stdin and return the sum of those numbers. Currently it only processes the first number on each line. Besides positive numbers, it also handles negative numbers and numbers with decimals.
-i Only return the integer portion of the final sum.
-I Only return the decimal portion of the final sum.
-c Print out the sum of each column.
-r Print out the sum of each row.
-x <n> Specify a comma seperated list of columns to print.
-y <n> Specify a comma seperated list of rows to print.
-s <string> Specify a string to use as a seperator for columns.
This defaults to be consecutive whitespace (\s+).
-h Help: You're looking at it.
-V Increase verbosity.
-d Debug mode. For developers
-q Quiet mode, don't print any warnings.
Simply add up the numbers in a file.
