yann@1722: 		    --stable, -s, +x   (default)
yann@1722: 		      mark the version as being stable (as opposed to experimental, below)
yann@1722: 		
yann@1722: 		    --experimental, -x, +s

yann@1722: 		
yann@1722: 		    add experimental obsolete version 2.3.5 and stable current versions 2.6.1
yann@1722: 		    and 2.6.2 to glibc, add stable obsolete version 3.3.3 to gcc:
yann@1722: 		      ${myname} --glibc -x -o 2.3.5 -s -c 2.6.1 2.6.2 --gcc -o 3.3.3
