    --gcc, --binutils, --glibc, --eglibc, --uClibc, --linux,
yann@245

  Valid options for all tools:
yann@1173
    19
    --stable, -s, +x   (default)
yann@1173
    20
      mark the version as being stable (as opposed to experimental)
yann@43
    21
yann@1173
    22
    --experimental, -x, +s
yann@1173
    23
      mark the version as being experimental (as opposed to stable)
yann@1173
    24
yann@1173
    25
    --current, -c, +o   (default)
yann@1173
    26
      mark the version as being cuurent (as opposed to obsolete)
yann@1173
    27
yann@1173
    28
    --obsolete, -o, +c
yann@1173
    29
      mark the version as being obsolete (as opposed to current)
yann@1173
    30
yann@1173
    31
  Note: setting a new tool resets to the defaults: 'stable' and 'current'.

  'version' is a valid version for the specified tool.

  Examples:
yann@1173
    36
    add stable current version 2.6.19.2 to linux kernel:
yann@858
    37
      ${myname} --linux 2.6.19.2
yann@1
    38
yann@1173
    39
    add experimental obsolete version 2.3.5 and stable current versions 2.6.1
yann@1173
    40
    and 2.6.2 to glibc, add stable obsolete version 3.3.3 to gcc:
yann@1173
    41
      ${myname} --glibc -x -o 2.3.5 -s -c 2.6.1 2.6.2 --gcc -o 3.3.3
