expack - manipulate Flex files SYNOPSIS
expack -a FLEXFILE FILE... expack -c FLEXFILE FILE... expack -x FLEXFILE [INDEX] expack -i MANIFEST expack -l FLEXFILE DESCRIPTION
expack is a command-line utility that lets you extract and create Flex files. Flex files are archives (which means that they act as con- tainers for other files, somewhat like directories) used by Ultima 7 to store most of its data. Note that the names of the original files are not stored in the Flex -- files are only retrievable by their index. Modes of operation -a Add --NOT IMPLEMENTED YET. FUTURE ENHANCEMENT-- This command adds one or more FILEs to the end of FLEXFILE. -c Create This command takes one or more FILEs and bundles them into FLEXFILE, overwriting it in the process. -x Extract Lets you extract the files contained within FLEXFILE. If INDEX is given only the file at this position will be unpacked, otherwise all files are extracted. The created files will be named index.u7o. -i Input Similar to "Create", this command creates FLEXFILE from a number of input files. However, "Input" takes the names of the input files from MANIFEST instead of the command line. MANIFEST must be a list of file names, one per line. The first name is that of the Flex file that is to be created, the rest are the input files used in building it. -l List This command lists the contents of a FLEXFILE. It gives you the number of files contained within the Flex file, as well as the length of each file. EXAMPLES
expack -a animals.flx bee.wav Adds bee.wav to the Flex file animals.flx. expack -a animals.flx hamster.wav snake.wav donkey.wav Adds hamster.wav, snake.wav, and donkey.wav to the Flex file animals.flx. expack -c animals.flx duck.wav cat.wav cow.wav dog.wav Creates a new Flex file animals.flx containing duck.wav, cat.wav, cow.wav, and dog.wav. expack -x text.flx 17 Extracts the file at position 17fromtext.flxinto17.u7o. expack -x text.flx Extracts all files from text.flx into files named 0.u7o, 1.u7o, 2.u7o, etc. expack -i wavlist With wavlist reading: jmsfx.flx ant.wav bee.wav cat.wav will create a new Flex file jmsfx.flx consisting of ant.wav, bee.wav, andcat.wav. expack -l text.flx Lists the number and lenghts of files contained in text.flx.

The "Add" command (-a) does not work yet. AUTHOR

qwavcut - extract and/or delete parts of a wav file SYNOPSIS
qwavcut [option]... file DESCRIPTION
qwavcut allows to extract and/or delete a fragment of a wav file. some parameters must be supplied in order to define the start/size/end cut points and what to do then: either the fragment must be copied to another file or erased from the file (or both) GENERAL OPTIONS
-d, --delete deletes the fragment from the file. if option --output is used, deletion action is always done after fragment extraction. -h, --help show a brief help and exit. -o <outfile>, --output=<outfile> outfile is the file where the samples contained in the specified cut will be copied. -V, --version show version and exit. CUT OPTIONS
cut options are used to specify at which sample the fragment begins (options -b or -B), ends (options -e and -E), or which size it has (option -s). at least, one cut option must be specified. neither the options -b and -B, and the options -e and -E can be used together; also, a begin, end and size option can be used at the same time. by default, the fragment begins at the first sample and ends at the last sample; there's no default value for size. all the values are treated as a sample number unless a format specifier is used. see the FORMATS section below for information. all values must be positive integer. -b <begin>[<format>], --set-begin-from-eof=<begin>[<format>] begin specifies the first sample of the file that belongs to the cut counting from the end of the file. -B <begin>[<format>], --set-begin=<begin>[<format>] begin specifies the first sample of the file that belongs to the cut counting from the beginning of the file. -e <end>[<format>], --set-end-from-eof=<end>[<format>] end specifies the last sample of the file that belongs to the cut counting from the end of the file. -E <end>[<format>], --set-end=<end>[<format>] end specifies the last sample of the file that belongs to the cut counting from the beginning of the file. -s <size>[<format>], --set-size=<size>[<format>] size specifies the number of samples contained in the cut. -S <begin>-<end>, --slice <begin>-<end> slice specifies the starting and ending points of the cut as a timeslice, which is to say, two time specifications ([[h:]m:]s[.ms]) joined by a hyphen. FORMATS
cut options can have also an optional modifier. if this modifier is not used, then the value provided with the corresponding cut option will be interpreted as a number of samples. since most of the times will be difficult to specify a cut in terms of samples, the following modifiers are provided: j value is interpreted as milliseconds. m value is interpreted as minutes. s value is interpreted as seconds. b value is interpreted as bytes. k value is interpreted as kbytes (1024 bytes). M value is interpreted as megabytes (1024 kbytes). in either case, the values specified will be rounded to get an integer number of samples. EXAMPLES
here are some examples: to get the last ten seconds of a file: qwavcut -b 10s -o outfile.wav infile.wav four ways of getting the first minute of a file: qwavcut -S -1:0 -o outfile.wav infile.wav qwavcut -S -60 -o outfile.wav infile.wav qwavcut -E 1m -o outfile.wav infile.wav qwavcut -s 1m -o outfile.wav infile.wav four ways of getting the second quarter of a file: qwavcut -S 15:0-30:0 -o outfile.wav infile.wav qwavcut -B 15m -E 30m -o outfile.wav infile.wav qwavcut -s 15m -E 30m -o outfile.wav infile.wav qwavcut -B 15m -s 15m -o outfile.wav infile.wav NOTES
if neither the options --output nor --delete are specified, the program will do nothing. when cutting at the end, a simple truncate call is needed. but when cutting in the middle or in the beginning, all the data behind the cut must be moved ahead and, depending on the amount of the data to be moved, this can be a time consuming operation. BUGS
tests has been done only with 44100 Hz 16 bit stereo files, though it may work with mono/stereo 8/16 bits files. AUTHOR
