This directory contains these utilities: - hxascdmp: takes a binary stream and converts it to hexadecimal ASCII which is sent to stdout. The incoming binary stream can either be from a file or, in the absence of a file name, from stdin. Similar to the Unix "od" command. By default, it decodes 16 bytes per line with an ASCII interpretation to the right of each line. See its hxascdmp(1) man page. - sg_chk_asc and tst_sg_lib: are no longer here, they have been moved to the 'testing' directory (a sibling of this directory). By default, the Makefile only builds the hxascdmp utility. The 'Makefile' file (i.e. with no suffix) builds for Linux; the 'Makefile.freebsd' file builds for FreeBSD (e.g. 'make -f Makefile.freebsd'); the 'Makefile.solaris' file builds for Solaris; the 'Makefile.mingw' builds in the Windows MinGW environment (e.g. msys shell); and 'Makefile.cygwin' builds in the Windows Cygwin environment.
