#: * `diy` [`--name=`<name>] [`--version=`<version>]:
#: Automatically determine the installation prefix for non-Homebrew software.
#:
#: Using the output from this command, you can install your own software into
#: the Cellar and then link it into Homebrew's prefix with `brew link`.
#:
#: The options `--name=`<name> and `--version=`<version> each take an argument
#: and allow you to explicitly set the name and version of the package you are
#: installing.
