This template is intended to handle the case where a library has many components within it (examples of this include CPAN, RubyGems and Tcllib). It has two required parameters: <tt><nowiki>{{</nowiki>uses from|</tt>''library''<tt>|</tt>''component''<tt><nowiki>}}</nowiki></tt>. The ''library'' is the name of the overall library of components (which should also be the name of a category here on RC) and the ''component'' is the name of the component within it (which can be almost any string).

==Discussion==
This template is derived from {{tmpl|tcllib}}, and seeks to have a similar aim, except more generically, and as a potential eventual replacement for {{tmpl|libheader}} and {{tmpl|works with}}. (And {{tmpl|tcllib}}, if it achieves sufficient functionality.)

===What it does===
* Associates the page with the library:
** Semantically, as <tt><nowiki>[[Uses library::{{{1}}}]</nowiki></tt>
** As part of <tt>[[:Category:{{{1}}}]]</tt> (though this may eventually change)
** By linking to <tt>[[Library/{{{1}}}]]</tt>.
* Associates the page with each component specified
** Semantically, as <tt><nowiki>[[Uses library::{{{1}}}/{{{componentN}}}]]</nowiki></tt> (Placing the component as a subpage of the library
** By linking to <tt><nowiki>[[Library/{{{1}}}/{{{componentN}}}]]</nowiki></tt>.

===What it needs to do (eventually)===
* Associate library version information with the page.
* Associate component version information with the page.

===What it should do===
* Avoid using MediaWiki categories as possible.

The richer the relationships we can define, the more powerful the search options we'll have available.
