- 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).
