# Makefile.common
#
# This file, to be included from every document's local Makefile, provides
# the basic targets used by the Fedora Docs Project.  To see a list,
# type "make help".

# STYLE GUIDE (Or, How To Keep Tommy From Raising A Single Eyebrow At You)
# 1) Lines are 80 characters, max.
# 2) Tabs are 8 characters, exactly.
# 3) All targets must use the "::" form to allow multiple instances of
#    the target.
# 4) Keep a modular Makefile.  For example, do NOT group all the "clean:"
#    rules into one place.  Using the "::" form lets us keep all the 
#    targets and rules for one object (file, template, whatever) close
#    together.  This makes maintenance much, much easier.
#########################################################################
# One key to writing good rules (the commands run to build a target) is
# to write the shell commands so they could be cut'n pasted into a real
# shell window.  To do this, we have to find a common pidgen syntax that
# works for both make(1) and the Bourne-type shells.
#
# Compared to even the most basic shell, the make(1) parser is very 
# limited.  This is most visible when referencing shell variables or
# make(1) macros.  While a shell only needs delimiters to disambiguate
# $FOObar from ${FOO}bar, make(1) needs the delimiters for any macro
# name longer than one character.  Combining the two rules, we get:
#
# 1) In a shell script, use the form ${FOO} to reference *EVERY* variable
#    instead of using $(FOO); most shells interpret the parens as a 
#    directive to run the contents in a subshell.  All shells correctly
#    handle the ${} braces form.
# 2) In a make(1) rule, use the form ${FOO} instead of $(FOO) when
#    referencing macros.
# 3) Reserve the form $(FOO), with parens, for enclosing real shell
#    commands such as $(shell /bin/pwd)
#########################################################################

#########################################################################
# Note: all targets within this Makefile.common must be defined as 
# double-colon (::) targets so that additional steps can be added by
# providing additional rules, also marked with double-colons, in the
# document Makefile.

# to all of the other generated product files.  THIS IS THE ONLY TARGET
# THAT WILL ERASE A .PO FILE!  Unless you are working on the I18N part

# voids all warranties!  It will never show up on a "make help" list!
