# If downloading this app separately (not as part of 
# an OTP source release), then there is two ways to
# build and install this app.
# 1) Replace the megaco source dir in an existing
#    OTP source tree. Then re-configure, build and 
#    install OTP.
#    Note that the directory name has to be renamed
#    from megaco-<version> to megaco.
# 2) Unpack outside an OTP-source tree. 
#    a) Configure app (make ERL_TOP=</path/to/top/OTP-source/dir> conf)
#    b) make ERL_TOP=</path/to/top/OTP-source/dir>
#    c) make ERL_TOP=</path/to/top/OTP-source/dir> \
#            OTP_INSTALL_DIR=</path/to/top/OTP-install/dir> app_install
#       (e.g. if otp is installed in /usr/local/otp-r9b,
#        then OTP_INSTALL_DIR is /usr/local/otp-r9b and
#        the app will be installed in dir 
#        /usr/local/otp-r9b/lib/erlang/lib/megaco-<version>)
