acquire-core-x/app/build.sh

#!/bin/bash
##
## build.sh - REUSABLE build + Enduro/X config generator for acquire-core-x.
##
## Discovers every module under app/src/<mod>/, ecpg-precompiles its .pgc, builds
##   - libacqcommon.a           (from app/src/common/*.c)          [once]
##   - lib<mod>dbio.a           (from app/src/<mod>/dbio/*.pgc)     [per module]
##   - <mod>_svr                (from app/src/<mod>/<mod>_svr.pgc)  [per module]
##   - <mod> batches            (from app/src/<mod>/batch/*.pgc)    [per module]
##   - standalone clients       (from app/src/clients/*.c)
## then GENERATES app/conf/ndrxconfig.xml with one <server> entry per <mod>_svr.
##
## Adding a new module later = drop app/src/<mod>/{<mod>_svr.pgc,dbio,batch} and
## re-run build.sh. No hand-editing of config or this script is required: modules,
## servers, dbio libs, batches, and srvids are all DISCOVERED.
