English英语译成Chinese汉语 技术/工程设计 IT（信息技术） IBM Eclipse

One of the important values of the Eclipse platform is that, unlike early Java applications that were quite frankly ***looked like they were drawn with a crayon*** and had to create all their own windowing, all their own menu systems, and all their own users interfaces, Eclipse RCP understands that is it going to be operating on one of the major operating systems platforms Windows, Linux, or Macintosh, and takes advantage of all of the native windowing and application services just like somebody would write an application a specific solutions application, but it provides that middle-ware layer so that people can actually write to the Eclipse platform and get the cross operating systems capabilities automatically.

looked like they were drawn with a crayon 像粉笔画？什么意思？
