= tycker - a web-based ticker input form =
tycker offers a very simple interface to be used for entering ticker information.
Each entry consists of the current time, a title and content.
The content may be written in wikicreole syntax:
http://www.wikicreole.org/imageServlet?page=CheatSheet%2Fcreole_cheat_sheet.png
The data items are stored in an sqlite database by default. Other options
(mysql/postgres) are easily configurable, as well.
The result is processed via the template "display.html". Adjust this file to
generate the desired layout.
Generated html files are stored in the parent directory of tycker's base directory.
