Makefile

all: snippet

#
# The name of the binary(ies) you want to build if `make` is invoked without an
# explicit target - which is so important it gets to go on the first line. On
# to business: the purpose of this Makefile is to let you build Haskell
# programs with a minimum of fuss. You should be able to type
#
# $ make
#
# and have ./stormy be built; this will happen if and only if there is a
# Haskell source file with a lower-cased named and a main in it by that name in
# src/. This also works with lower-cased source files in tests/:
#
# $ make check
#
# will build ./check from tests/check.hs.
#
# As wired, src/ binaries are built tight and tests/ binaries are built with
# profiling enabled.
#

#
# GHC makes a lot of temporary files. Where to put them?
#

# Haskell compiler and build options. As specified here we always build with
# the full threaded runtime and GHC profiling enabled, 'cause, you need those
# things.
