# This script builds in debug mode and installs openresty together with the
# ngx_http_voms_module.
#
# The script requires the locations of the openresty bundle and of the
# ngx_http_voms_module code (for example as checked-out from git). The locations
# are expressed by the environment variables OPENRESTY_ROOT and
# NGX_HTTP_VOMS_MODULE_ROOT respectively, if available. If they are not set,
# they are guessed:
# * a unique openresty bundle is looked for in ${HOME}
# * the ngx_http_voms_module code is looked for in the working directory of the
#   continuous integration environment first and then in ${HOME}
#
# The script works best (i.e. it is tested) if run within a docker container
# started from the storm2/ngx-voms-build image.

#The script at the moment allows only debug builds, i.e. "-O0". This option is kept in shell variables cc2, but there is no way to set it to something else. I propose that by default it is set to -O2 (or even -O3) and is set to -O0 only if the option --debug is passed to the script. Moreover --coverage should imply --debug.
