# This script serves two purposes. First, it can bootstrap the standalone
|
||||
# Blueprint to generate the minibp binary. To do this simply run the script
|
||||
# with no arguments from the desired build directory.
|
||||
#
|
||||
# It can also be invoked from another script to bootstrap a custom Blueprint-
|
||||
# based build system. To do this, the invoking script must first set some or
|
||||
# all of the following environment variables, which are documented below where
|
||||
# their default values are set:
|
||||
#
|
||||
# BOOTSTRAP
|

# WRAPPER

# SRCDIR
|

# BUILDDIR

|
||||
# GOROOT
|
||||
# GOOS
|
||||
# GOARCH
|
||||
# GOCHAR
|
||||
#
|
||||
# The invoking script should then run this script, passing along all of its
|
||||
# command line arguments.
