description block造句

• Specify dot directives outside a description block , at the start of a line
  点指令在描述块之外的行首指定点指令。
• A description block is a dependency line optionally followed by a commands block
  描述块是后面可跟有命令块的依赖项行：
• Inference rules can build a command - line target even if no description block exists
  即使不存在描述块，推理规则也可以生成命令行目标。
• Nmake looks for a matching inference rule if a description block is not followed by a commands block
  如果描述块后面没有紧跟命令块， nmake将查找匹配的推理规则。
• If a description block s target has no dependents or commands , an inference rule can update the target
  如果描述块的目标没有依赖项或命令，推理规则可以更新目标。
• A description block or inference rule specifies a block of commands to run if the dependency is out - of - date
  如果依赖项已过期，则描述块或推理规则指定要运行的命令块。
• If a dependent file does not exist and is not listed as a target in another description block , an inference rule can create the missing dependent from another file with the same base name
  如果依赖文件不存在，并且未在另一个描述块中作为目标列出，则推理规则可以从具有相同基名称的另一个文件创建缺少的依赖项。
