--   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.
