CLISP手册

Question

我想从REPL或者只是从shell阅读clisp函数的帮助。我为它找到了(symbol-plist)函数，它给出了这个：

(symbol-plist 'bit)
(SYSTEM::TYPE-SYMBOL #<COMPILED-FUNCTION SYSTEM::TYPE-SYMBOL-BIT>
 SYSTEM::SETF-EXPANDER SYSTEM::STORE SYSTEM::DOC
 (CLHS "Body/any_bit.html" SYSTEM::FILE
  ((DEFSETF #P"/build/buildd/clisp-2.49/debian/build/places.fas" 941 941))))

但对于理解(bit)是如何工作的，它并不是那么有用的信息？

那么有没有类似于man in shell的clisp函数的手册和文档呢？

在这里，这可能会引起人们的兴趣。下面是一个简短的摘录：

函数位数组和rest下标

bit与aref完全相同，但需要一个位数组，即一个类型(数组位)。结果将始终是0或1。sbit类似bit，但另外要求第一个参数是一个简单的数组(参见2.5节)。请注意，与char和schar不同，bit和sbit允许第一个参数是任意秩的数组。
