#BUILDING MOSES
#
#PACKAGES
#Language models (optional):
#--with-irstlm=/path/to/irstlm 
#--with-srilm=/path/to/srilm See moses/LM/Jamfile for more options.
#--with-randlm=/path/to/randlm
#KenLM is always compiled.  
#
#--with-boost=/path/to/boost
#If Boost is in a non-standard location, specify it here.  This directory is
#expected to contain include and lib or lib64.  
#
#--with-xmlrpc-c=/path/to/xmlrpc-c for libxmlrpc-c (used by server)
#Note that, like language models, this is the --prefix where the library was
#installed, not some executable within the library.  
#
#Compact phrase table and compact lexical reordering table
#--with-cmph=/path/to/cmph
#
#Thread-caching malloc (if present, used for multi-threaded builds by default)
#--without-tcmalloc
#
#REGRESSION TESTING
#--with-regtest=/path/to/moses-reg-test-data
#
#INSTALLATION
#--prefix=/path/to/prefix sets the install prefix [default is source root].
#--bindir=/path/to/prefix/bin sets the bin directory [PREFIX/bin]
#--libdir=/path/to/prefix/lib sets the lib directory [PREFIX/lib]
#--includedir=/path/to/prefix/include installs headers.  
#  Does not install if missing.  No argument defaults to PREFIX/include .
#--install-scripts=/path/to/scripts copies scripts into a directory.
#  Does not install if missing.  No argument defaults to PREFIX/scripts .
#--git appends the git revision to the prefix directory.
#
#
#BUILD OPTIONS
# By default, the build is multi-threaded, optimized, and statically linked.  
# Pass these to change the build:
#
# threading=single|multi         controls threading (default multi)
#
# variant=release|debug|profile  builds optimized (default), for debug, or for
#                                profiling
#
# link=static|shared             controls preferred linking (default static)
# --static                       forces static linking (the default will fall
#                                back to shared)
#
# debug-symbols=on|off           include (default) or exclude debugging
#                                information also known as -g
# --notrace                      compiles without TRACE macros
#
# --enable-boost-pool            uses Boost pools for the memory SCFG table
#
# --enable-mpi                   switch on mpi
# --without-libsegfault          does not link with libSegFault
#
# --max-kenlm-order              maximum ngram order that kenlm can process (default 6)
#
# --max-factors                  maximum number of factors (default 4)
#
#CONTROLLING THE BUILD
#-a to build from scratch
#-j$NCPUS to compile in parallel
#--clean to clean
