${bold}NAME${normal}
    ${bold}deploy.sh${normal} - script to deploy sisoputnfrba's TP.

${bold}SYNOPSIS${normal}
    ${bold}deploy.sh${normal} [ ${bold}-t${normal}=${underline}target${nounderline} ] [ ${bold}-s${normal}=${underline}structure${nounderline} ] [ ${bold}-r${normal}=${underline}rule${nounderline} ] [ option=${underline}value${nounderline}... ] ${underline}repository${nounderline}

${bold}DESCRIPTION${normal}
    The ${bold}deploy.sh${normal} utility is to ease the deploy process.

${bold}POSITIONAL ARGUMENTS${normal}
    ${bold}-t | --target${normal}       Changes the directory where the script is executed. By default it will be the current directory.

    ${bold}-s | --structure${normal}    Changes the path where the script should look for makefiles. By default it will be the current directory of each project.

    ${bold}-r | --rule${normal}         Changes the makefile rule for building projects. By default it will be 'all'.

${bold}OPTIONS${normal}
    ${bold}-l | --lib${normal}          Adds an external dependency to build and install.

    ${bold}-d | --dependency${normal}   Adds an internal dependency to build and install from the repository.

    ${bold}-p | --project${normal}      Adds a project to build from the repository.

    ${bold}-c | --config${normal}       Replaces a variable in all configuration files containing it. The format is 'key=value'.

${bold}COMPATIBILITY${normal}
    The repository must be in ${bold}sisoputnfrba${normal} organization and have makefiles to compile each project or dependency.

${bold}EXAMPLE${normal}
