#

# == Links

#

# marks" followed immediately by a colon and the URL of the link.

# attribute for the link, visible as a tool tip when a cursor is above it.

# Example:

#

#  "This is a link (This is a title) ":http://www.textism.com

# Will become:

#  <a href="http://www.textism.com" title="This is a title">This is a link</a>

#

# == Images

#

# To insert an image, put the URL for the image inside exclamation marks.

#

# browsers.

#

# closing ! to make the image into a link.

# Example:

#

#  !http://www.textism.com/common/textist.gif(Textist)!

#

# == Defining Acronyms

#

# this should be used at least once for each acronym in documents where they appear.

#

# immediately following the acronym.

# Example:

#

#  ACLU(American Civil Liberties Union)

#     (background:#ddd;color:red). |{}| | | |

# Textile formatting.  Use it like a String and output HTML with its

# RedCloth#to_html method.
