" [FLAGS] [PATH|FLEXDEC...] [<<<FLEXDEC...\\n...]\n\
Turns numbers into decimal with commas.\n\
\n\
Values are tokenized by spaces. Anything that isn't an integer is\n\
passed through. We parse integers the same way the C compiler does\n\
so 0x,0b,0,etc. prefixes are fine. Unicode spacing characters are\n\
supported.\n\
\n\
Flags:\n\
-o PATH output path\n\
-F STR\n\
-T STR sets field tokenization charset [default is whitespace]\n\
-w FLEXDEC\n\
-n FLEXDEC set fixed number of columns [default is variable, based\n\
on line breaks]\n\
-?\n\
-h shows this information\n\
