---|
269 | # - Look at `pear list` for Pear fruits (or whatever they're called). |
---|
270 | # Yet again, 'yum search' for RPMs before resorting to 'pear install'. Note |
---|
271 | # that for things in the beta repo, you'll need 'pear install package-beta'. |
---|
272 | # (you might get complaints about the php_scripts module; ignore them) |

275 | # pecl/foo' or 'pecl install foo-beta' or creating a root-readable-only file |
