Thanks, I've made some tweaks and pushed this to master as
85f4d87b8154238480dc176b77b8c54dde84e1c4.

As the linter points out, "the source file name should contain the
package name".

I tweaked the indentation above.

> +    (home-page "http://smem.sourceforge.net")

As the linter points out, this page doesn't currently work. As the
source is being fetched from selenic.com, I changed the homepage
accordingly.

> +    (description
> +"This package provides a command line tool that can give numerous reports
> +on memory usage on GNU/Linux systems.")

I also tweaked the indentation above.
