#! /usr/bin/env bash
# Upgrade remote packages in a bdep-managed build2 toolchain build (default
# configurations), essentially as if by executing:
#
# bdep sync -fur && b
#
# In each project of the toolchain.
#
# Note that we can't just do that because as soon as we drop some dependency
# package, the tools (b, bppg, etc) become non-runnable (missing shared
# libraries, etc).
#
# Finally, this script only upgrades the default configurations (including
# -libs, if present). To upgrade the rest you can use the normal way, for
# example:
#
# bdep sync -fur @<cfg>|-a
#
# If the -c option is specified, the configuration is upgraded and configured
# but only the build system is updated. This can be done at a later stage by
# running the build system in the configuration directory:
#
# BDEP_SYNC=0 b
#
