# WARNING: This may or may not work on your system. This Makefile is
# an example, rather than a ready-made universal solution.
#
# This Makefile builds and installs Subversion, and many of its
# dependencies, on UNIX-like systems, in the current working directory.
# Indirect dependencies are not covered, e.g. you need OpenSSL installed
# to get SSL support in neon and serf.
#
# The Makefile can also run Subversion's regression test suite via all
# repository backends and RA methods. It generates the necessary configuration
# files and starts svnserve and httpd daemons automatically on non-privileged
# ports.
#
# Some version of Subversion is required to be in $PATH and will be used
# to check out working copies.
#
# The default is to compile trunk.
# Pass the branch you want to build in BRANCH, e.g.
#	$ make BRANCH="1.5.x"
# You can also pass a tag to build:
#       $ make TAG="1.6.6"
# And you can specify a working copy to use, in case you need more
# than one working copy of the same branch:
#	$ make BRANCH="1.6.x" WC="1.6.x-test2"
#
# After the build, point your PATH to the Subversion build you want to use.
# Note that this Makefile requires GNU make.
