11# These are some unix tools that are commonly included in the /usr/bin
12# and /usr/sbin directory under more normal distributions. Along with
13# coreutils, these are commonly assumed to be available by build
14# systems, but we can't assume they are available. In Nix, we list
15# each program by name directly through this unixtools attribute.
16
17# You should always try to use single binaries when available. For
18# instance, if your program needs to use "ps", just list it as a build
19# input, not "procps" which requires Linux.
