Manure... 

There are tools for it but ext2/3/4 and some of the other file systems
have allocation algorithms and I/O scheduling policies that make them
fragmentation resistant. If you plot fragmentation and performance over
time they don't drop off very much even after years of I/O (at least for
almost all workloads...). btrfs on the other hand currently seems to have
chronic fragmentation problems.

So it's nothing to do with tools, its a design property, the core of
which comes from the BSD FFS/UFS work in the 1980s. Various other
improvements have been added on top of that including block reservations.
