求助 allegro -nograph -s xxx.psx 什么意思？

这两个是运行参数，-nograph的帮助文档说明：
Command switch for UNIX platforms only that runs the tool in a non-graphic mode but still requires an X display. This switch can also be typed -nograph.
-s在windows下是安全模式运行。

谢谢，还有一个疑问，生成shape symbol脚本中，内容简易如下：# Allegro script
#   file: C:\Users\xx\Desktop\QFN50P900X900X80-65AN\cmplxrr0-3x0-8a0.psx
#   start time: Mon, Jan 4 2:41:36 2016
version 16.5

newdrawfillin "cmplxrr0-3x0-8a0.dra" "Shape Symbol"
setwindow pcb

……
运行脚本，却打开的却是package  symbol  ，是脚本不对吗?
