.SH SYNOPSIS

.SH "OUTPUT FORMATS"

The rustdoc tool can generate output in an HTML format.

If using an HTML format, then the specified output destination will be the root
directory of an HTML structure for all the documentation.
Pages will be placed into this directory, and source files will also
possibly be rendered into it as well.

.SH "EXAMPLES"

To generate documentation for the source in the current directory:
    $ rustdoc hello.rs

List all available passes that rustdoc has, along with default passes:
    $ rustdoc \-\-passes list

The generated HTML can be viewed with any standard web browser.
