Here is a brief description of the files included in this directory:

PKGBUILD.vim - a vim/gvim syntax file for PKGBUILDs. Colors known variable
names, highlights common errors such as invalid characters in pkgname or
pkgver, etc.

bash_completion - a bash completion script for pacman, install in
/etc/bash_completion.d/ for use (but rename to something descriptive!).

zsh_completion - a zsh completion script, install (with a rename) to
/usr/share/zsh/site-functions/.

pacdiff - a simple pacnew/pacorig/pacsave updater for /etc/.

paclist - list all packages installed from a given repository. Useful for
seeing which packages you may have installed from the testing repository,
for instance.

pacscripts - tries to print out the {pre,post}_{install,remove,upgrade}
scripts of a given package.

pacsearch - a colorized search combining both -Ss and -Qs output. Installed
packages are easily identified with a *** and local-only packages are also
listed.

pactree - generate a dependency tree of an installed package in textual or
graphical form (using graphviz).

bacman - regenerate a pacman package based on installed files and the pacman
database entries. Useful for reuse, or possible config file extension.

vimprojects - a project file for the vim project plugin.

wget-xdelta.sh - A download script for pacman which allows binary deltas
generated with makepkg to be used instead of downloading full binary packages.
This should cut download sizes for some package upgrades significantly.
