===== Components =====

==== Tag ====

  {{tag>[list of tags]}}

^ [list of tags] | a space separated list of tags that describe the content of the current page | required |

Allows you to categorize your wiki pages. The resulting links point to the corresponding page in the specified tag namespace. If you want a link to point to a page in another namespace, you have to indicate the namespace before the tag name.

Examples:
  * ''%%{{tag>tag1 tag2 tag3}}%%'' 
  * with namespaces: ''%%{{tag>:ns1:tag1 ns1:tag2 ns2:subns1:tag3}}%%'' 



==== Topic ====

  {{topic>[tag]&[flags]}}

^ [tag] | the category tag for which you want a list of pages | required |
^ [flags] | pagelist flags delimited by ''&'', see [[pagelist#flags]] | optional |

This displays a list of all pages that contain the given category tag. The list is sorted alphabetically by page ID. You can also prepend the modifiers ''+'' and ''-''. ''+'' creates an intersection between the list of pages created by the already defined tags and the pages matching the tag following the ''+'' (AND), ''-'' removes all pages tagged with the given tag from the list of already found pages.

Example: 
  * ''%%{{topic>tag1 -tag2}}%%'' -- Lists all pages tagged with tag1 but not with tag2.
  * ''%%{{topic>tag1 +tag2}}%%'' -- Lists all pages tagged with tag1 and tag2.
  * ''%%{{topic>tag1 tag2}}%%'' -- Lists all pages tagged with either tag1 or tag2 or both.
