DESCR="C Language Decision Table Code Generator"

LONG_DESCR="Ccide reads a source code file containing\
embedded decision tables from STDIN, analyzes and expands each of the\
tables. All statements not within a decision table are copied unchanged\
to STDOUT, generating a compilable C source module. Erratic side effects\
are avoided by evaluating all condition expressions exactly once and by\
performing evaluations and actions in the original sequence."

# Conformance checks:
#you need to add an explicit invocation of ‘AC_USE_SYSTEM_EXTENSIONS’ in the configure.ac file - after ‘AC_PROG_CC’ but before ‘AM_GNU_GETTEXT’, most #likely very close to the ‘AC_PROG_CC’ invocation. This is necessary because of ordering restrictions imposed by GNU autoconf.
