Subject: Added README.Debian.plugins.in and gen_plugin_deps.pl.
X-Git-Tag: collectd-4.2.0-1~21
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=113b61864abec15606317396446d6bf36178966f;p=pkg-collectd.git

Added README.Debian.plugins.in and gen_plugin_deps.pl.

The script gen_plugin_deps.pl generates a list of dependencies for each
plugin requiring anything besides libc6. README.Debian.plugins.in and this
list are then used to create README.Debian.plugins which is included in
the collectd binary package.

 General notes:
 --------------
 
-- This package is split up into several packages to prevent you from having to
-  install dependencies that you don't actually need. Any plugin that has 
-  dependencies other than libc gets its own package.
+- Some plugins require additional libraries. To prevent you from having to
+  install dependencies that you don't actually need those libraries are
+  recommendations rather than dependencies. See README.Debian.plugins in the
+  "collectd" package for details.

+collectd plugins on Debian
+==========================
+
+Some plugins require additional libraries. To prevent you from having to
+install dependencies that you don't actually need those libraries are
+recommendations rather than dependencies.
+
+apt-get(8) and aptitude(8) will install recommended packages automatically by
+default. If you did not disable this feature you will have everything in place
+to operate all plugins. Else you have to install missing dependencies manually
+(see the section "Plugin dependencies" below).
