#: * `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.

of #{canonical_name.inspect}. Consider using the canonical name instead:

brew diy --name=#{canonical_name}

brew diy --name=#{detected_name}
