sac2c -h and sac2c -help now provide the same debug information, instead of being different.
Namely, they print:

SAC - Single Assignment C
---------------------------------------------------------------------------
Name: sac2c
Version: 2.0.0-Tintigny-66-g15bb7-dirty
The sac2c compiler transforms SAC source code into executable programs
(SAC programs) or into a SAC specific library format (SAC module and
class implementations), respectively.
The compilation process is performed in 4 separate stages:
1. sac2c uses any C preprocessor to preprocess the given SAC source;
while doing so we expose some internals via debug-flags:
SAC_BUILD_STYLE=<xyz>
SAC_BACKEND_<xyz>
SAC_BACKEND_STRING="<xyz>"
SAC_TARGET_<xyz>
SAC_TARGET_STRING="<xyz>"
SAC_RC_<resource-entry>=<val> for all numeric entries
2. sac2c itself transforms preprocessed SAC source code into C code;
3. sac2c uses any C compiler to generate target machine code;
4. sac2c uses any C linker to create an executable program
or sac2c itself creates a SAC library file.
When compiling a SAC program, sac2c stores the corresponding
intermediate C code either in the file a.out.c in the current directory
(default) or in the file <file>.c if <file> is specified using the -o
option. Here, any absolute or relative path name may be used.
The executable program is either written to the file a.out or to any
file specified using the -o option.
However, when compiling a SAC module/class implementation, the
resulting SAC library is stored in the files <mod/class name>.a
and <mod/class name>.so in the current directory.
In this case, the -o option may be used to specify a
different directory but not a different file name.

BUGS:
Bugs?? We????
SAC is a research project!
SAC tools are platforms for scientific research rather than
"products" for end users. Although we try to do our very best,
you may well run into a compiler bug. So, we are happy to receive
your bug reports (Well, not really "happy", but ...).To print a specific subsection (help page), one can use sac2c -h thename or sac2c -help thename.
For example, features
