\t$NAME - Build delivery using the ${BOLD}local host system${RESET}.
${BOLD}SYNOPSIS${RESET}
\t$NAME [-h|--help|help] [examples|dotnet|java|python|all|reset]
${BOLD}DESCRIPTION${RESET}
\tBuild Google OR-Tools deliveries.
\tYou ${BOLD}MUST${RESET} define the following variables before running this script:
\t* ORTOOLS_TOKEN: secret use to decrypt keys to sign .Net and Java packages.

${BOLD}OPTIONS${RESET}
\t-h --help: display this help text
\tdotnet: build all .Net packages
\tjava: build all Java packages
\tpython: build all Pyhon packages
\texamples: build examples archives
\tall: build everything (default)

${BOLD}EXAMPLES${RESET}
Using export to define the ${BOLD}ORTOOLS_TOKEN${RESET} env and only building the Java packages:
export ORTOOLS_TOKEN=SECRET
$0 java

note: the 'export ...' should be placed in your bashrc to avoid any leak
of the secret in your bash history
