# Generates cross builds for all supported platforms.
#
# This script is used to build binaries for all supported platforms. Cgo is
# disabled to make sure binaries are statically linked. Appropriate flags are
# given to the go compiler to strip binaries. Current git tag is passed to the
# compiler by default to be used as the version in binaries. These are then
# compressed in an archive form (`.zip` for windows and `.tar.gz` for the rest)
# within a folder named `dist`.
