| 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 |
