The file you get is 'tar'ed and compressed using the UNIX 'compress' utility.
The size of the compressed file is about 400 kB.
Uncompressing and unpacking it, a directory 'ASC.21' with the subdirectories 'EXAMPLES', 'SCRIPTS', 'README', 'lib' and 'src' will be created.
ASC.21 contains two files, 'asc.call' and 'asc.make'; starting asc.call will do all the nescessary steps to create the executable 'asc'.
For more information see the manuals in the 'README' directory.
