DECOMMENT
Remove "#" comment lines

DECOMMENT is a C++ program that makes a copy of a file in which all lines beginning with the "#" character have been removed.

It is a comment convention to indicate comments in a file by an initial "#" character. I often use this convention in my data files, and it is part of the TABLE format. However, certain hard-hearted or soft-headed programs will not accept comment lines. The DECOMMENT program allows me to comment my data files, but then to easily make an uncommented version, when necessary, to feed to illiterate programs.
