Well, it's really an all or nothing thing. And all's going to be a pain
until we're sure we aren't going to have to go back and edit the
history.

You're indenting with two spaces rather than four, and don't have our
precious vim modelines. Lack of consistency makes me cry!

I'm wondering whether we can tone this (and the similar wording in PMS)
down a bit. The Council approved PMS as "correct, except where people
file bugs" a while back.

Spelling of 'explicitly'.

Not sure on this wording. How about something like:

    SRC_URI="http://some/url -> foo" can be used to use foo as the
    filename for downloads.

    Dependencies can specify use flag requirements on their target,
    removing the need for built_with_use checks. A more powerful syntax
    that does not require the flag to be in IUSE is in EAPI 3.

    Patching and similar preparation must now be done in src_prepare,
    not src_unpack.

    so duplicating the standard implementation is no longer necessary.
    The default function calls the current phase's default_ function
    automatically.

    Most checks should usually be repeated in pkg_setup.

    Be warned that dependencies might not have been installed.

Braces are {}. You want brackets or parentheses.

    The former specifies that flags not in IUSE should be treated as
    enabled; the latter, disabled. Cannot be used with USE_EXPAND flags.

    docompress path ... adds paths to the inclusion list for
    compression. docompress -x path ... adds paths to the exclusion
    list.

"in the known manner" sounds weird.

I'd mention that commands die on error before this. And then:

    will return non-zero on failure rather than aborting the build.

    use? ( ) blocks are forbidden as direct children of || ( ) blocks.

'anymore' as a single word is generally considered horrible.

OK, but won't apply easily without 0001, and I'm lazy.

Applied, thanks.

Applied, thanks.
