DESCRIPTION

   The ::vfs package includes a library of Tcl code, implementing a number
   of different virtual filesystems.  Each of  these  exists  as  its  own
   package,  and  can  be accessed through package require vfs::NAME.  The
   whole set of virtual filesystems is known informally as 'vfslib'

SUPPORTED VFS TYPES

   The current supported types are ftp, tar, http, zip, mk4,  ns,  webdav.
   In  addition  there  is  the  ability  to  mount any 'urltype' as a new
   volume, provided an appropriate vfs is supported.  This means that  you
   can treat 'ftp://', 'http://' and 'file://' urls as files.  To do this,
   simply evaluate the command

   vfs::urltype::Mount ftp

   for instance.  Any access inside the  new  volume  will  result  in  an
   attempt  to  require  a package through 'package require vfs::${type}',
   which must therefore exist, or errors will be thrown.

LIMITATIONS

   Most of the vfs types listed above have not been very well debugged  as
   yet.  Please test them!

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.



Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Books


The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.



Education


Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
