layman是一种overlay manager,Overlays 的添加通常是通过编辑/etc/make.conf的 PORTDIR_OVERLAY="" 来管理,但是在sabayon是使用Layman进行管理。

在终端输入:

layman --help(灰色使用频率较高)

显示如下:

Usage:

layman -a/-d/-S|overlay
layman -f [-o url]
layman -l|-L

其中

layman -S的作用类似emerge --sync 更新syncs下所有已经安装的overlays
Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit

  <Actions>:
    -a ADD, --add=ADD   Add the given overlay from the cached remote list to
                        your locally installed overlays.. Specify "ALL" to add
                        all overlays from the remote list.
    -d DELETE, --delete=DELETE
                        Remove the given overlay from your locally installed
                        overlays. Specify "ALL" to remove all overlays
    -s SYNC, --sync=SYNC
                        Update the specified overlay. Use "ALL" as parameter
                        to synchronize all overlays
    -i INFO, --info=INFO
                        Display information about the specified overlay.
    -S, --sync-all      Update all overlays.
    -L, --list          List the contents of the remote list.
    -l, --list-local    List the locally installed overlays.
    -f, --fetch         Fetch a remote list of overlays. This option is
                        deprecated. The fetch operation will be performed by
                        default when you run sync, sync-all, or list.
    -n, --nofetch       Do not fetch a remote list of overlays.
    -p PRIORITY, --priority=PRIORITY
                        Use this with the --add switch to set the priority of
                        the added overlay. This will influence the sorting
                        order of the overlays in the PORTDIR_OVERLAY variable.

  <Path options>:
    -c CONFIG, --config=CONFIG
                        Path to the config file [default:
                        /etc/layman/layman.cfg].
    -o OVERLAYS, --overlays=OVERLAYS
                        The list of overlays [default:
                        http://www.gentoo.org/proj/en/overlays/layman-
                        global.txt].

  <Output options>:
    -v, --verbose       Increase the amount of output and describe the
                        overlays.
    -q, --quiet         Yield no output. Please be careful with this option:
                        If the processes spawned by layman when adding or
                        synchronizing overlays require any input layman will
                        hang without telling you why. This might happen for
                        example if your overlay resides in subversion and the
                        SSL certificate of the server needs acceptance.
    -N, --nocolor       Remove color codes from the layman output.
    -Q QUIETNESS, --quietness=QUIETNESS
                        Set the level of output (0-4). Default: 4. Once you
                        set this below 2 the same warning as given for --quiet
                        applies!
    -k, --nocheck       Do not check overlay definitions and do not issue a
                        warning if description or contact information are
                        missing.

  <Debugging options>:
    Control the debugging features of layman

    --debug             Activates debugging features.
    --debug-level=DEBUG_LEVEL
                        A value between 0 and 10. 0 means no debugging
                        messages will be selected, 10 selects all debugging
                        messages. Default is "4".
    --debug-verbose=DEBUG_VERBOSE
                        A value between 1 and 3. Lower values yield less
                        verbose debugging output. Default is "2".
    --debug-methods=DEBUG_METHODS
                        Limits the methods that will return debugging output.
                        The function name is sufficient and there is
                        nodifference between class methods or general
                        functions. Several methods can be specified by
                        seperating them w with a comma. Default is "*" which
                        specifies all methods.
    --debug-classes=DEBUG_CLASSES
                        Limits the classes that will return debugging output.
                        Specify only the class name not including the modules
                        in which the class is defined (e.g. MyModule.main.Main
                        should only be represented by "Main"). Severalclasses
                        can be specified by seperating them with a comma.
                        Default is "*" which specifies all classes.
    --debug-variables=DEBUG_VARIABLES
                        Limits the variables that will return debugging
                        output. Several variables can be specified by
                        seperating them with a comma. Default is "*" which
                        specifies all variables.
    --debug-class-vars  In default mode the debugging code will only return
                        information on the local variable which does not
                        include the class variables. Use this switch to add
                        all values that are provided by "self".
    --debug-nocolor     Deactivates colors in the debugging output.
