Usage: ${myname} <--tool> <[options] version [...]> ...
|
|
'tool' in one of:
|
|
gcc, binutils, glibc, eglibc, uClibc, newlib, linux, gdb, dmalloc,
|
|
duma, strace, ltrace, libelf, gmp, mpfr, ppl, cloog, mpc
|
|
|
|
Valid options for all tools:
|
|
--stable, -s, +x (default)
|
|
mark the version as being stable (as opposed to experimental, below)
|
|
|
|
--experimental, -x, +s
|
|
mark the version as being experimental (as opposed to stable, above)
|
|
|
|
--current, -c, +o (default)
|
|
mark the version as being cuurent (as opposed to obsolete, below)
|
|
|
|
--obsolete, -o, +c
|
|
mark the version as being obsolete (as opposed to current, above)
|
|
|
|
Note: setting a new tool resets to the defaults: 'stable' and 'current'.
|
|
|
|
'version' is a valid version for the specified tool.
|
|
|
|
Examples:
|
|
add stable current version 2.6.19.2 to linux kernel:
|
|
${myname} --linux 2.6.19.2
|
|
|
|
add experimental obsolete version 2.3.5 and stable current versions 2.6.1
|
|
and 2.6.2 to glibc, add stable obsolete version 3.3.3 to gcc:
|
|
${myname} --glibc -x -o 2.3.5 -s -c 2.6.1 2.6.2 --gcc -o 3.3.3
