# Builds the project
build:

# Builds distribution - uses xgo and the docker container for cross platform builds with CGO (due to Sqlite bindings)
# See: https://github.com/crazy-max/xgo - (previously was https://github.com/karalabe/xgo)
#    docker pull crazymax/xgo:latest
#    go install github.com/crazy-max/xgo@latest
# Note that this will download and build the latest version of package from github - it won't build the local go
# repo. So you need to have published everything (and ensure tags are as desired) before doing this.
# Temp workaround for problem with xgo docker on M3 not building Linux amd64 - use local version.
# For details see: https://github.com/crazy-max/xgo/issues/124
