+# Builds a new campaignd or wesnothd binary from source.
+#
+# Usage:
+#    update_server [-c] <server version> [<revision>]
+#
+#    -c    Builds campaignd instead of wesnothd
+#
+# SCons is used to build the source code from SOURCE_ROOT (no write access
+# required) onto INT_ROOT. The resulting binary and ancillary files are stored
+# in DEST_ROOT in a subdir specific to that build's version and revision (e.g.
+# 'wesnothd-trunk-git-<revision id>', where <revision id> corresponds to the
+# output of `git describe`).
+#
+# Additionally, the symbolic link ~/bin/wesnothd-<version> or
+# ~/bin/campaignd-<version> (depending on the -c switch) is updated to point
+# to the newest binary for that version.
