Arch Linux

Description: cairo is not a split package and has only a simple package()
function in its PKGBUILD. The depends=() line should be in the normal
location in the head of the file as described in the Arch Wiki entry for
PKGBUILD and as is uniform practice. At present the depends line for
the cairo PKGBUILD is inside the package() function.

It looks like this is an accident after some editing; the depends line in
the normal location was commented (in preparation for splitting?).

I notice this because I use an awk script to parse all PKGBUILDs and have
to assume some reasonable standard syntax for the file. There may be two
schools of thought here: PKGBUILD is a declarative file that happens to also
be a valid bash script, and PKGBUILD is just a bash script and anything that
bash accepts is ok.

I raise this as a bug because the "it's just a bash script" approach will
make it difficult in the long run to develop good ancilliary tools for
processing the Arch "database" of packaging definitions.

I hope that the authors agree with me and will continue to keep PKGBUILDs
"clean and tidy" and as declarative as possible.
