It used to be that you could write emerge --help --verbose to see detailed information about all options, but since a while ago, this just prints the same short help as emerge --help. Last working version seems to be 2.2.0_alpha59, in alpha60 it started printing the short output.
Yes, it was removed in order to avoid duplication. We could make it call `man 1 emerge` automatically.
Ah, in this case, the --help output should probably have this line changed; emerge --help [ --verbose ]
(In reply to comment #2) > Ah, in this case, the --help output should probably have this line changed; > > emerge --help [ --verbose ] Okay, this is fixed in git: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=94fadd2ba5296976657c005ab88be691a4e7af29
This is fixed in 2.1.11.53 and 2.2.0_alpha164.
