Please add a technical overview to your introduction. As a techie, I
would like to read what is so special about zerotools what I cannot do
rm crapfiles && cat /dev/zero > bigfile && sync && rm bigfile && sync.
And you introduction does not tell me about anything new in your tools
and I do not like reading a long novel to learn that simple details.
Zerotools are a set of tools to aid keeping virtual disks clean (by
filling binary zero to those regions which are no longer in use as
visible files). In technical terms, they contain a library wrapper used
with LD_PRELOAD to make unlink calls zero-out the data before unlinking
the files and helper executables based on it.
