* This program will not prompt you to insert the disks if it doesn't
* need to, so have the correct disks in the correct drives before
* hitting the `Go' gadget!
*
* This is dfc, a disk copying and formatting utility written by Radical
* Eye Software. This program is in the public domain; anyone can do
* anything they want with it. This software is made available on an as-is
* basis; don't come to me if you destroy your entire fish disk library
* with it! Of course, it was tested rather extensively before it was
* released . . .
*
* This code was written with Manx 3.4b on February 8, 1988.
*
* dfc is meant to replace both format and diskcopy, and be smaller than
* either. It is meant to work exactly the same as either, depending on
* the command line arguments you give it. In addition, it has several
* additional options, such as buffering of a disk for a quick additional
* copy, the ability to toggle verify mode on and off, and the ability to
* write to multiple disks at the same time. It also has a nice Intuition
* interface. It will not replace the `DiskCopy' or `Format' options from
* the workbench, however; these have to work with the Workbench startup
* message, which this program does not.
*
* This program can be invoked with no command line options. In this case,
* it defaults to a diskcopy from df0: to df1: with verify on and buffering
* on. All keyword options can be preceded by a dash, for you Unix lovers
* out there, and can be abbreviated to one character. The following
* parameters are accepted:
*
* f[rom] disk Use `disk' as the source drive. The format for disk
* is completely free; only the numerals in the argument
* are looked at.
* t[o] disks Use `disks' as the destination drives. Again, the
* format is unspecified.
* v[erify] Verify all writes (default).
* nov[erify] Turn off the verify mode.
* b[uffer] Use extra buffer memory. If your system has enough
* memory, an entire disk will be cached in RAM.
* Otherwise, almost all of the system memory will be
* used.
* nob[uffer] Do not buffer; use minimum memory. (Default.)
* n[ame] diskname Format the destination disk with name `diskname'.
* Otherwise a diskcopy is assumed.
* d[...] A drive argument. Might not have a d; simple numbers
* work as well. The first occurance of such an argument
* sets the source and destination fields; a subsequent
* occurance only sets the destination.
*
* Thus,
* dfc df0: name "Foo bar baz"
* formats drive df0: and names the resultant disk "Foo bar baz".
* dfc df0: df1:
* diskcopies from df0: to df1:.
* dfc -nov 0 123
* diskcopies from drive 0 to drives 1, 2, and 3, with verify turned off.
* dfc from df0: to df0:,df1:,df2:,df3:
* diskcopies from drive df0: to all four drives.
* dfc name Foo
* formats drive df1 with the name "Foo".
*
* Once the program opens its window up, you will have a bunch of gadgets.
* The left-most column of gadgets is the source selection; here you can
* choose either format, or one of the four drives. The next column is
* the destination column; choose any combination of the four drives by
* clicking on the gadgets. Lines will be drawn between these two columns
* indicating the current selections. If a drive is not available, no line
* will be drawn to it.
*
* The topmost gadget is the name gadget. This is used to set the name of
* your disk while formatting.
*
* The `Go' gadget starts the program up; you had better have the disks in
* the drives when you hit this gadget! The `Again' gadget makes another
* copy of the last disk, if buffering is on and enough buffers were
* allocated for an entire disk. This gadget requires all destination
* disks to be in their drives already.
*
* The `Retry' gadget tells the system to retry after a disk error. The
* `Quit' gadget tells the system to abort an operation; you can hit this
* at an error, which aborts the current operation; you can hit this during
* a copy or format operation, which does the same; or you can hit this
* with the drives inactive, which exits the program.
*
* The `Verify' gadget turns the verify mode on and off. The `Buffer'
* gadget turns buffering on and off.
*
* All of these gadgets have keyboard shortcuts which are simply the first
* letter of the gadget name. The source gadgets can be selected with the
* digits `0', `1', `2', or `3'; the destination gadgets with the shifted
* versions of these keys (')', `!', `@', and `#'.) The carriage return
* key is a synonym for `Go', for added diskcopy and format compatibility.
*
* Enjoy this program! Please send any bug reports to Tomas Rokicki,
* Box 2081, Stanford, CA 94309.
