-# Recursive stuff

-# At the top of the file so that recursive makes happen before
-# makes in the main directory. This is needed for some targets,
-# e.g. when building DLLs in hslibs.

-##################################################################
-
-# Here are the diabolically clever rules that
-#
-# (a) for each "recursive target" <t>
-# propagates "make <t>" to directories in SUBDIRS
-#
-# (b) when SUBDIRS is empty,
-# for each "multi-way-target" <t>
-# calls "make -way=w <t>" for each w in $(WAYS)
-#
-# This has the effect of making the standard target
-# in each of the specified ways (as well as in the normal way
-
-# Controlling variables
-# WAYS = extra (beyond the normal way) ways to build things in
-# SUBDIRS = subdirectories to recurse into
-
-# No ways, so iterate over the SUBDIRS
-
-# note about recursively invoking make: we'd like make to drop all the
-# way back to the top level if it fails in any of the
-# sub(sub-...)directories. This is done by setting the -e flag to the
-# shell during the loop, which causes an immediate failure if any of
-# the shell commands fail.
-
-# One exception: if the user gave the -i or -k flag to make in the
-# first place, we'd like to reverse this behaviour. So we check for
-# these flags, and set the -e flag appropriately. NOTE: watch out for
-# the --no-print-directory flag which is passed to recursive
-# invocations of make.
-#
-# NOTE: Truly weird use of exit below to stop the for loop dead in
-# its tracks should any of the sub-makes fail. By my reckoning,
-# "cmd || exit $?" should be equivalent to "cmd"

# GNU Standard targets
#
# `all'
# Compile the entire program. This should be the default target.
-# This target need not rebuild any documentation files; Info files
-# should normally be included in the distribution, and DVI files
-# should be made only when explicitly asked for.
+# This target need not rebuild any documentation files
#
# `install'
# Compile the program and copy the executables, libraries, and so on
# will ignore any errors. This is in case there are systems that
# don't have the Unix man page documentation system installed.
#
-# The way to install Info files is to copy them into `$(infodir)'
-# with $(INSTALL_DATA) (see Command Variables), and then run the
-# install-info program if it is present. install-info is a script
-# that edits the Info `dir' file to add or update the menu entry for
-# the given Info file; it will be part of the Texinfo package. Here
-# is a sample rule to install an Info file:
-#
-# $(infodir)/foo.info: foo.info # There may be a newer info
-# file in . than in srcdir.
-# -if test -f foo.info; then d=.; \
-# else d=$(srcdir); fi; \ $(INSTALL_DATA)
-# $$d/foo.info $@; \ # Run install-info only if it
-# exists. # Use `if' instead of just prepending `-' to the
-# # line so we notice real errors from install-info. # We
-# use `$(SHELL) -c' because some shells do not # fail
-# gracefully when there is an unknown command.
-# if $(SHELL) -c 'install-info --version' \
-# >/dev/null 2>&1; then \ install-info
-# --infodir=$(infodir) $$d/foo.info; \ else true;
-# fi
-#
# `uninstall'
# Delete all the installed files that the `install' target would
# create (but not the noninstalled files such as `make all' would
# Delete everything from the current directory that can be
# reconstructed with this Makefile. This typically includes
# everything deleted by distclean , plus more: C source files
-# produced by Bison, tags tables, Info files, and so on.
+# produced by Bison, tags tables, and so on.
#
# One exception, however: `make maintainer-clean' should not delete
# `configure' even if `configure' can be remade using a rule in the
# `TAGS'
# Update a tags table for this program.
#
-# `info'
-# Generate any Info files needed. The best way to write the rules is
-# as follows:
-#
-# info: foo.info
-#
-# foo.info: foo.texi chap1.texi chap2.texi
-# $(MAKEINFO) $(srcdir)/foo.texi
-#
-# You must define the variable MAKEINFO in the Makefile. It should
-# run the makeinfo program, which is part of the Texinfo
-# distribution.
-#
-# `dvi' `ps'
-# Generate DVI files for all TeXinfo documentation. For example:
-#
-# dvi: foo.dvi
-#
-# foo.dvi: foo.texi chap1.texi chap2.texi
-# $(TEXI2DVI) $(srcdir)/foo.texi
-#
-# You must define the variable TEXI2DVI in the Makefile. It should
-# run the program texi2dvi , which is part of the Texinfo
-# distribution. Alternatively, write just the dependencies, and
-# allow GNU Make to provide the command.
+# `dvi' `ps' `pdf' `html' `pdf'
+# Generate DVI/PS/PDF files for LaTeX/DocBook docs. Not everything is
+# supported everywhere, but the intention is to standardise on DocBook
+# producing all formats.
#
-# ps is a FPtools addition for Postscript files
-#
-# `dist' `binary-dist'
-# Create a distribution tar file for this program. The tar file
-# should be set up so that the file names in the tar file start with
-# a subdirectory name which is the name of the package it is a
-# distribution for. This name can include the version number.
-#
-# For example, the distribution tar file of GCC version 1.40 unpacks
-# into a subdirectory named `gcc-1.40'.
-#
-# The easiest way to do this is to create a subdirectory
-# appropriately named, use ln or cp to install the proper files in
-# it, and then tar that subdirectory.
-#
-# The dist target should explicitly depend on all non-source files
-# that are in the distribution, to make sure they are up to date in
-# the distribution. See Making Releases.
-#
-# binary-dist is an FPtools addition for binary distributions
-#
# `check'
# Perform self-tests (if any). The user must build the program
# before running the tests, but need not install the program; you

-# dist-pre is a canned rule the toplevel of your source tree
-# would use as follows,
+# Targets: check tags show
#
-# dist :: dist-pre
-#
-# it performs two tasks, first creating the distribution directory
-# tree and it then decorates the new tree with symbolic links pointing
-# to the symbolic links in the build tree.
-#
-# The dist-pre relies on (at least) the `find' in GNU findutils
-# (only tested with version 4.1). All non-GNU `find's I have
-# laid on my hands locally, has a restrictive treatment of {} in
-# -exec commands, i.e.,
-#
-# find . -print echo a{} \;
-#
-# does not expand the {}, it has to be a separate argument (i.e. `a {}').
-# GNU find is (IMHO) more sensible here, expanding any {} it comes across
-# inside an -exec, whether it is a separate arg or part of a word:
-#
-# $ touch yes
-# $ find --version
-# GNU find version 4.1
-# $ find yes -exec echo oh,{}! \;
-# oh,yes!
-#
-# Of course, the above is not impossible to achieve with other finds,
-# just that GNU find does the Patently Right Thing here :)
