  - HCL VersionVault build concepts
    HCL VersionVault supports makefile based building of software systems and provides a software build environment closely resembling that of the make program.
  - Derived objects and configuration records
    Learn about derived objects and configuration records.
  - Pointers on using HCL VersionVault build tools
    Learn how to use VersionVault build tools.
  - Working with DOs and configuration records
    You can perform operations on derived objects and configuration records.
  - clearmake makefiles and BOS files
    The HCL VersionVault build program, clearmake can process makefiles.
    - Makefile overview
      A makefile contains a sequence of entries, each of which specifies a build target, some dependencies, and the build scripts of commands to be executed.
    - Build options specification files
      A build options specification (BOS) file is a text file containing macro definitions and/or HCL VersionVault special targets.
    - Format of makefiles
      Understand the special considerations for using makefiles with clearmake.
      - Restrictions
        Read the restrictions imposed by clearmake.
      - Libraries
        Learn about libraries.
      - Command echoing and error handling
        You can control the echoing of commands and the handling of errors that occur during command execution on a line-by-line basis or on a global basis.
      - Built-In rules
        File name extensions (suffixes) and their associated rules in the makefile override any identical file name extensions in the built-in rules.
      - Include files
        Learn how a makefile is interpreted with strings.
      - Macros
        From this content, you will understand the order of precedence of macros in a clearmake build, and the different types of macros.
      - Special targets
        Like other build tools, clearmake interprets certain target names as declarations. Some of these special targets accept lists of patterns as their dependents, as noted in the description of the target.
    - Sharing makefiles between UNIX or Linux and Windows
      You can share makefiles between UNIX, Linux, and Windows.
    - BOS file entries
      You can put some entries in BOS files.
    - Conflict resolution
      Learn how to resolve conflicts that can occur in specifications of make macros and environment variables.
    - SHELL environment variable
      Learn about the SHELL environment variable.
    - CCASE_BRANCH0_REUSE environment variable
      Understand the use of the CCASE_BRANCH0_REUSE environment variable.
  - Using clearmake compatibility modes
    clearmake is designed for compatibility with existing make programs, which minimizes the changes you need to make to your makefiles.
  - Using HCL VersionVault to build C++ programs
    Use clearmake effectively with C++ programs built with various compilers.
  - Using HCL VersionVault build tools with Java
    The build behavior of Java tools causes various problems for clearmake. Understand the problems and some possible solutions to resolve them.
  - Setting up a parallel build
    Learn the process to set up and run builds that use several hosts in the local area network.
  - Building software for multiple platforms
    Learn how to address the challenge of using a single source tree to develop an application for a variety of hardware and software platforms.
  - Setting up a build on a non-VersionVault host
    There is a technique to create configuration records for a build that involves HCL VersionVault data, but is performed on a non-VersionVault host.
