292 <p>Laconica comes bundled with a number of libraries required for the application to work. However, it is best that you use PEAR or you distribution to manage
293 libraries instead, as they tend to provide security updates faster, and may offer improved performance.</p>
294 <p>On Debian based distributions, such as Ubuntu, use a package manager (such as "aptitude", "apt-get", and "synaptic") to install the package listed.</p>
295 <p>On RPM based distributions, such as Red Hat, Fedora, CentOS, Scientific Linux, Yellow Dog Linux and Oracle Enterprise Linux, use a package manager (such as "yum", "apt-rpm", and "up2date") to install the package listed.</p>
296 <p>On servers without a package manager (such as Windows), or if the library is not packaged for your distribution, you can use PHP's PEAR to install the library. Simply run "pear install <name>".</p>
