#
# Jamrules -- build configurations
#
# The default build is for debugging. To compile a release
# build, add -sBUILD=release to the jam command line. To provide
# a custom build you can use any name you want instead of release
# or debug.
#
# JBIG2 and JPEG2000 support is optional. To compile with this,
# add the following to the jam command line:
#
#   -sHAVE_JBIG2DEC=true
#   -sHAVE_JASPER=true
#
# Windows builds assume that third party headers and
# libraries are in c:/local/include and c:/local/lib.
#
# MacOS X builds assume that you have third party libraries installed
# from MacPorts in /opt/local.
#
# Linux builds assume that you have freetype-config to find the paths
# to the freetype library.
#
# To override these defaults, please supply the paths on the jam
# command line with -sTHIRDPARTINC and -sTHIRDPARTYLIB.
#
#   -sTHIRDPARTYINC="-Ic:/wherever/include"
#   -sTHIRDPARTYLIB="-Lc:/wherever/lib"
#
# To compile without builtin CJK CMap and font support, and save a few
# megabytes of executable space:
#
#   -sDEFINES=NOCJK 
#
