@appendix Glossary
@cindex Glossary

@c Confused? You obviously haven't read enough! :-)

@c Note from Angela: the German Glossary contains much more entries than
@c the English Glossary since I am explaining the meaning of many German
@c computer words which some people possibly don't know (because they
@c are reading too many English computer books. So if you think
@c an explanation of the words _you_ are using in _your_ language should
@c appear in the glossary, feel free to add them!
@c Please sort the glossary alphabetically.

Sorry, this glossary is not yet finished. A lot of expressions still
have to be explained.

@item Bug Report
@cindex Bug Report
Larger projects invariable contain some ugly errors which the user may
encounter at some time.
In such cases, we ask that the user submit a @dfn{Bug Report}.
This is a description of the error which has been encountered.
Check the circumstances under which the error occurs and write down
everything!
Note the @emph{exact} version of @value{programname} which you are using
and the configuration of your computer.


@item CD-ROM image
@cindex CD-ROM image
CD-ROMs, but disks, hard disks or just single partitions can be written
to a single file, by means of ``unrolling'' them so that the file
contains blocks starting from the lowest (0) through to the
highest-numbered block at the end. Such a file contains a @dfn{Disk
Image}. At some time thereafter, the file can be written to a CD-R to
yield an exact copy of the original CD-ROM. The CD-ROM has, in principle,
been copied.

However, if you want to save data from a hard disk to a CD-R, you can
@emph{not} just copy the image of the hard disk to CD-R. That's why you
need the image creation part of MakeCD: it scans one or more directory
trees and creates an CD-ROM image file that can be written to a CD-R and
yields to a valid CD-ROM.


@item Coffee Break
@cindex Coffee Break
A coffee break is that amount of time required by a program to do a
particular task in background. Most of the time, there's no precise
indication of how long this is. Sometimes, it won't be long enough to get
the kettle to boil, yet at other times, you'll have enough time to invite
the neighbours around to share the latest gossip over some cake.

I'd like to take this opportunity to apologize to those who may have been
misled that a @emph{single} cup of coffee was sufficient, by my comments
on @dfn{Meeting @w{Pearls III}}. Of course, a @emph{bucket} of coffee was
what I meant. :-)


@item Device Unit
@cindex Device Unit
See @dfn{Unit}.


@item Device Driver
@cindex Device Driver
Every hard drive and every CD writer requires a @dfn{Device Driver} so
that it can be used in the @value{AMIGA} in a system-conformant way. This
driver is responsible for reading data from, and writing data to the CD
writer, amongst other tasks. Devices drivers have a name ending in
@code{.device}. For example; @code{scsi.device}, @code{gvpscsi.device},
@code{omniscsi.device}, @code{z3scsi.device}, @code{dracoscsi.device},
etc.


@item Installer Script
@cindex Installer Script
A unified method of installation for all software packages on the
@value{AMIGA} was developed to make this as simple as possible. Every
package includes a plain-text file --- the Installer script --- to be
interpreted by the Installer program at installation time to make the
installation process as independent as possible of the prior knowledge of
the user.


@item Meeting Pearls
@cindex Meeting Pearls
You don't know about Meeting Pearls? That's got to be fixed straight
away! Meeting Pearls is Germany's most popular CD-ROM series for the
@value{AMIGA} as well as being extremely good value for money as the
creators don't demand any payment for their work @footnote{although
donations are most welcome :-)}, so only direct production and
distribution costs need to be paid. As you most likely have a CD-ROM
drive or a CD writer, it's well worth a look.


@item mkisofs
@cindex mkisofs
A program which is quite popular on Unix system and which is used to
create @dfn{CD-ROM images}.


@item Program Icon
@cindex Program Icon
Many programs have an icon --- a small symbol on which you can click when
it appears on the Workbench. Icons belonging to programs are called
@dfn{program icons}. Further information about this can be found in your
Workbench manual.


@item Progress Indicator
@cindex Progress Indicator
The @dfn{progress indicator} indicates what proportion of work has been
done by the use of a bar graph. On occasions, this indicator will move at
a very uneven rate. This will always occur if the it wasn't possible to
pre-compute how long the particular operation would take or if your system
is too busy to update the GUI elements.


@item Rock Ridge extensions
@cindex Rock Ridge extensions
@dfn{Rock Ridge extensions} have been defined for Unix machines, because
under Unix --- like on the @value{AMIGA}, too --- there are some file
attributes which have been unknown on those MS-DOS machines and so were
not included in the ISO9660 standard. Rock Ridge extensions are
extensions on ISO9660. Every correctly written CD-ROM, which has Rock
Ridge extensions, can be also read by filesytems that don't support Rock
Ridge. However, most likely some objects will look different.

Angela Schmidt and some other persons have created a new @value{AMIGA}
standard, that enables mastering software to write Amiga attributes for
every single object on the CD-ROM to the CD-ROM. This is done by defining
another Rock Ridge extension. Of course, @value{MakeCD} supports this
special Rock Ridge extension, too.


@item Unit
@cindex Unit
@cindex Device Unit
A particular device, which is usually connected to the SCSI bus, is
identified by its @dfn{unit} or @dfn{device unit}. Valid unit numbers are
typically between 0 and 6 for SCSI devices. If you have any external SCSI
device, this may have a switch for setting a number. The number is
usually the unit number of the device. The comfortable device requester
of @value{programname} shows you all devices that are connected to the
SCSI bus.


@item Volume Name
@cindex Volume Name
The @emph{formatted} name of a disk or partition is the @dfn{volume
name}. This name is also visible on the @cite{Workbench} screen.
@value{programname} can write such a volume name into an ISO 9660 image,
if you are a registered user. However, according to the ISO 9660 specs,
in ISO Level 1 or 2, only upper case characters, digits and the
underscore are allowed in the volume name.
