--- | Module containing some specialized functions to deal with tags.
--- This Module follows certain conventions. Stick with them.
---
--- More concrete: all functions in this module assume that the tags are
--- located in the @tags@ field, and separated by commas. An example file
--- @foo.markdown@ could look like:
---
--- > ---
--- > author: Philip K. Dick
--- > title: Do androids dream of electric sheep?
--- > tags: future, science fiction, humanoid
--- > ---
--- > The novel is set in a post-apocalyptic near future, where the Earth and
--- > its populations have been damaged greatly by Nuclear...
---
--- All the following functions would work with such a format. In addition to
--- tags, Hakyll also supports categories. The convention when using categories
--- is to place pages in subdirectories.
---
--- An example, the page @posts\/coding\/2010-01-28-hakyll-categories.markdown@
--- Tags or categories are read using the @readTagMap@ and @readCategoryMap@
--- functions. Because categories are implemented using tags - categories can
--- be seen as tags, with the restriction that a page can only have one
--- category - all functions for tags also work with categories.
---
--- When reading a @TagMap@ (which is also used for category maps) using the
--- @readTagMap@ or @readCategoryMap@ function, you also have to give a unique
--- identifier to it. This identifier is simply for caching reasons, so Hakyll
--- can tell different maps apart; it has no other use.
