Makefile: for Literate Haskell, Markdown/LaTeX mixed style

gistfile1.mak

# sauce of original Makefile magic:
#   http://passingcuriosity.com/2008/literate-haskell-with-markdown-syntax-hightlighting/
# modified by kgadek

# Ok, so I found Markdown+Bird style to be nice BUT editors have problems with Haskell code (indenting & stuff) when
# each line starts with ">".
# On the other hand LaTeX style is ok but LaTeX is often too powerful - distracts me all the time from actual code.

# But don't worry, I'm (nearly) an Engineer. Solution:
# Write Markdown style, enclose code with \begin{code}..\end{code} block and use small sed script to convert it to Markdown+Bird.
# What is cool, GHC does not complain at all!
