Console application to compress and extract files in the .val format, when
functional it can be used to replace tar files, the advantage is that it
will handle any previous versions without problems, it is almost as fast as tar,
for the moment it can generate .val files in gzip, bzip2, bzip3, lz5,
brotli2, lzop2, Zstandard, xz and LZMA, but more compression methods will
be added like our DLL version of this console application, a lot need
to be done yet
////////////////////////////////////////////////////////////////////
Header information for Parolin:
These compressors are available in the now outdated DLL
Parolin, the console version don´t support yet all these
compressors but will do it soon
the following information can be used to detect a compressed file
Notice that some formats like bzip3 and gzip2 have more than one
header for it, and you need to handle it
{ compress, 2, "\037\235" },
{ gzip, 2, "\037\213" },
{ bzip2, 3, "BZh" },
{ lzip, 4, "LZIP" },
{ lzma, 6, "\xFFLZMA" }, (this is not correct, lzma don`t
have a pre-defined header that
can be used to detect it, brotli too)
{ lzop, 4, "\211LZO" },
{ xz, 6, "\xFD" "7zXZ" },
{ lz4, 4, "\x04\x22\x4d\x18" },
{ zstd, 4, "\x28\xB5\x2F\xFD" },
{ val, 4, "\x56\x41\x4c\x50" },
{ gzip2a, 4, "\x52\x53\x50\x47" }, ( after release 5.1.7 this
don`t extract anymore)
{ gzip2c, 4, "\x41\x52\x5f\x5f" },
{ gzip2c, 4, "\x41\x52\x5f\x5E" },
{ bzip3, 4, "\x41\x52\x5f\x32" },
{ bzip3, 4, "\x41\x52\x5f\x5d" },
{ lzop2, 4, "\x41\x52\x5f\x53" },
{ lz5, 4, "\x41\x52\x5f\x56" },
{ brotli2, 4, "\x41\x52\x5f\x55" },
{ compress2, 4, "\x41\x52\x5f\x54" },

about debugging, many bugs fixed.
What is new in version 0.3.5 build 0057 12/jul/2023 05:11

minor bugs fixed.

Fixed a bug that was allowing a file already compressed to be
handled as if correctly compressed, now the compressed file
is deleted on entering the compression to avoid it having
the wrong data on it, the compression compress demonstarated
the bug, and now the basic tests are done as soon some modification
is done in the code to don´t brake anything already working,
minor bugs fixed.

truncated to 2 gb, fixed in this release, many bugs fixed.
