<title>Install Functions Reference</title>
<body>

<p>
The following functions are provided by the package manager to handle various
install-related tasks. <c>${ED}</c> is prepended automatically to the install location.
</p>

<p>
The <c>do*</c> functions, when given multiple arguments, will work upon multiple
targets. The <c>new*</c> functions take exactly two arguments (except as noted) <d />
the first is the source name, the second the name to use when installing.
</p>

<p>
The <c>*into</c> functions create the directory if it does not already exist.
</p>
