Multilib 和 Multiarch：这两个术语只是同义词吗？如果不是，它们有何不同？
如果我想在同一个系统中运行 32 位和 64 位应用程序，那么我应该将其称为Multiarch 还是 Multilib ？
我multiarch启用了，当我运行时debtags search，我得到了很多重复的结果。
$ debtags search 'works-with-format::man' | head
docbook-to-man - converter from DocBook SGML into roff man macros
docbook-to-man:i386 - converter from DocBook SGML into roff man macros
docbook-utils - Convert DocBook files to other formats (HTML, RTF, PS, man, PDF)
docbook2x - Converts DocBook/XML documents into man pages and TeXinfo
docbook2x:i386 - Converts DocBook/XML documents into man pages and TeXinfo
doclifter - Convert troff to DocBook
dwww - Read all on-line documentation with a WWW browser
dwww:i386 - Read all on-line documentation with a WWW browser
ebook-speaker - eBook reader that reads aloud in a synthetic voice
ebook-speaker:i386 - eBook reader that reads aloud in a synthetic voice
有一种解决方法grep：
$ debtags search 'works-with-format::man' | grep -v ':i386 - ' | head
docbook-to-man - converter from DocBook SGML into roff man macros
docbook-utils - Convert DocBook files to other formats (HTML, RTF, PS, man, PDF)
docbook2x - Converts DocBook/XML documents into man pages and TeXinfo
doclifter - Convert troff to DocBook
dwww - Read all on-line documentation with a WWW browser

git-man - fast, scalable, distributed revision control system (manual pages)
gman - small man(1) front-end for X

gnulib - GNU Portability Library
这假设该字符串:i386 -没有出现在任何包描述中，这有点骇人听闻。有没有更好的办法？
