In line with the Nixpkgs manual.
A mechanical change, done with this command:
find pkgs -name "*.nix" | \
while read f; do \
sed -e 's/description\s*=\s*"\([a-z]\)/description = "\u\1/' -i "$f"; \
done
I manually skipped some:
* Descriptions starting with an abbreviation, a user name or package name
* Frequently generated expressions (haskell-packages.nix)

|
|
The Apache Hadoop software library is a framework that allows for
|
|
the distributed processing of large data sets across clusters of
|
|
computers using a simple programming model. It is designed to
|
|
scale up from single servers to thousands of machines, each
|
|
offering local computation and storage. Rather than rely on
|
|
hardware to deliver high-avaiability, the library itself is
|
|
designed to detect and handle failures at the application layer,
|
|
so delivering a highly-availabile service on top of a cluster of
|
|
computers, each of which may be prone to failures.
