Documenting custom file roles
Standard file roles provided by default with PEAR are:
If your package chooses to use a role provided by a third party that implements some
more advanced file installation handling, all you need to do is specify the role in
the xml for the <file> tag that contains it like so:
However, if a user does not have the package installed that provides the custom role
"foo", then the error message on installation will simply say "unknown
role 'foo'", which is not very helpful.
The <usesrole> tag instead prompts the installer to tell the user "this package
uses the custom role 'foo', install package pear.example.com/Foo to use"
Note that static URI packages (channel-less packages) are also supported:
