## This is the pattern for the Makefile. It consists of several sections,
## every section begins with [name] on a single line, and ends where the
## next section starts. Inside the sections, variables are written as 
## [name], too.
## Comments that must not be copied to the output file begin with two
## hash marks.

[intro]
# ----------------------------------------------------------------------
# How to build the package [name]:
# ----------------------------------------------------------------------
# 
# make:                Same as "make all"
# make all:            Normally "make byte", but can also be set to "make opt"
# make byte:           Makes the bytecode archive and the bytecode executables
# make opt:            Makes the native archive and the native executable
# make install:        Install all installable files as package
# make uninstall:      Uninstall the package
# make clean:          Delete all files that can be remade
#
# The usual order of invocation is:
# - make byte
# - (optionally) make opt
# - make install
# - make clean
#
# You may want to give the -s option if you do not want to see the details
# of the build process (e.g. make -s all).
#
# ----------------------------------------------------------------------
# Important for developers
# ----------------------------------------------------------------------
# 
# This Makefile writes a copy of itself with appended dependencies.
# The copy is usually stored in the file .make-wizard.[makefile_name].
# If you want to invoke "make" for targets where the dependencies are
# involved, you have to specify -f .make-wizard.[makefile_name] on
# the command line, e.g.
#
# make -f .make-wizard.[makefile_name] sample.cmo
#
# Otherwise, the dependencies are ignored, and you get errors that are
# hard to explain.
#
# If you want to modify this Makefile, it is a good idea to put the
# modifications into a second file, and to enable the local Makefile
# extension in the wizard. This effects that the modifications are appended
# to this Makefile, so you can add rules and override variables without
# coming into conflict with the wizard.
