The program SNOW is used to conceal messages in ASCII text by appending
|
||||
whitespace to the end of lines. Because spaces and tabs are generally
|
||||
not visible in text viewers, the message is effectively hidden from
|
||||
casual observers.

# HOW TO EDIT THIS FILE:
|
||||
# The "handy ruler" below makes it easier to edit a package description.
|
||||
# Line up the first '|' above the ':' following the base package name, and
|
||||
# the '|' on the right side marks the last column you can put a character in.
|
||||
# You must make exactly 11 lines for the formatting to be correct. It's also
|
||||
# customary to leave one space after the ':' except on otherwise blank lines.
