-------------------------------------------------------------------------------
Acquiring the package:
The archive file contains a 'tar' file rather than the usual type of archive
to make it easy to unpack on non-RISC OS systems. To unpack use the following
command:
tar xvf nspark-1.7.5.tar
On RISC OS systems it should be possible to extract using SparkPlug 2 (see the
"tools_help" file in arch/riscos/tools for further info). To compile it you
will have to rename all the .c and .h files into separate c and h directories
unless you extract using the -s option of TAR (a/a052). A file is supplied to
do this for you.
Description:
Nspark can unarchive archives created by Archimedes Spark. It has
been writted with portability in mind and so can be compiled on
RISC OS, MS-DOS or UNIX machines. It has the following features:
o Supports all archive methods used by !Spark 1 and 2. The old
version didn't support "Squashing" and used to handle "Compressed"
archives by using the UNIX uncompress program. The new version
supports both these and has them built-in, allowing easier porting
to other OS's.
o Supports Cyclic Redundancy Checking (CRC). The integrity of an
archive can now be checked without having to unarchive it.
o Supports verbose option to allow archive file details to be
displayed (time/date or exec/load address, size, type).
o Supports selective file unarchiving, so the whole archive needn't
be unarchived if not all the files are wanted).
o Supports user-prompting before overwriting a file, allowing the
user to either (1) overwrite the file, (2) overwrite all the
files, (3) unarchive the file to a different name, or (4) not to
unarchive the file at all.
o Supports file-stamping so the date and time of the file, when
unarchived, matches the date and time it was archived (not 4.2BSD
or SysV.2 as these systems lack vital library functions).
Version 1.6 adds RISC OS support.
Version 1.7.4 adds support for extracting from ArcFS archives,
plus manual pages, and executables for popular
architectures.
Version 1.7.5 fixes a bug in the source code (included binaries
were not affected so remain as version 1.7.4).
