+This is a simple program which can join lines from stdin. The program is
+only 27 loc. I won\'t add features like pasting lines inside of a file.
+You can do everything just using stdin/stdout. Another advantage of this
+simple implementation that it does not use heap, only stack. This
+reduces the chance of getting corrupted memory. Althought This program
+provides better defaults (coma is the default separator), we sacrifice
+the speed for input containing many line. For that purpoce: use paste
