# The site is the base name of the SINGLE *.network-meta.xml file in the
# project. Prints that name (without the .network-meta.xml suffix) and exits 0.
# Exits non-zero with a message on stderr when zero or more than one such file
# exists — the reference implementation refuses to guess an ambiguous site.
#
# Usage: scripts/derive-site-name.sh [search-dir]
#   search-dir defaults to the current directory; the file is located
#   recursively, so both <packageDir>/main/default/networks/ and a project-root
#   networks/ layout resolve correctly.
