Is there any document regarding "__gnu_cxx::hash_map"?
I want to know how to use it.

The GNU implementation of hash_map is basically the same as the one described in the STL documentation.

This is the cousin of this question over here asking the same thing for C.
Basically, is there a better way than to just turn it into a giant byte array and putting it in a source file?
Alternatively, does a macro have the ability to do this? (Rust Macros... are a dense looking and their exact capabilities are not known to me.)
You probably want include_bytes!.
If you are in older versions of Rust, use include_bin! instead.
You could alternatively use this tool https://github.com/pyros2097/rust-embed Which was created by me which generates rust code for your resources.
I'm writing some *nix CLI utilities and I'd like to standardize my "--help" output for the various scripts, but I'm not sure what standards I should conform to.
I have only found this gnu.org standards reference but it doesn't provide any information on best practices / preferred format. Is there such a thing?
Is there any official spec or at least some pseudo-standards documentation I should try to adhere to?
I know this isn't a direct programming question, so let me know if there's another StackExchange it's better suited for.
Thanks!
Actually, not RFC but still a pretty good example of the conventional help output fromat could be found on docopt.org Even if you aren't going to use that DSL to implement your CLI interface, you really should read its documentation to get general ideas of 'standard' help.
Also you can find some useful information on Wikipedia and on opengroup.org
I searched everywhere from google to this site but seems no answer for it. Does anyone know if IronRuby supports clr class attributes? If yes, how?
Thanks in advance.
There's no way to apply CLR attributes in IronRuby today. IronPython support it experimentally with its clrtype module, which uses its own way of overriding the underlying .NET class for a Python object.
If one would want to implement this in IronRuby themselves, it'd be a large undertaking, but not impossible. If anyone is interesting, please ask about it on the mailing list to get started.
I am not clear about synchronisation and unsynchronisation in id3 tags.
I have read the developer info, but i could not able to understand.
Can you please help me in explaining the things clearly.
Thanks.
What more precisely you do not understand? It seems documentation is quite clear. The synchronisation can be used to some (in general legasy) programs, that do not know about ID3v2, does not accept tag data as frame header. By the way, it seems majority of programs does not use syncronisation, and possible if you faced with dificulties with synchronisation you can try do not work with synchronized tags.
I have tried to explain the unsynchronization scheme in a writeup here. In addition to the specifications you might want to have a look at http://phoxis.org/2010/05/08/what-are-id3-tags-all-about/#unsyncsafe
In a series of similar questions, what is the best AWK reference you've ever seen?
If there isn't really one (I've yet to find the grail), perhaps we could compile one in a separate question.
The AWK Programming Language, by Aho, Kernighan and Weinberger is the best. The initials of the author's names should tell you why...
I would recommend Effective AWK Programming by Arnold Robbins. You can get free pdf copy here.
Whenever I needed to know something about AWK I always went to my copy of UNIX in a Nutshell. Now I see that there is a SED/AWK in a Nutshell book and pocket guide. The former was enough for what I needed. Haven't used the latter two.
This reference card PDF is pretty comprehensive for a crib sheet, yet it's concise enough to allow you to find what you need quickly. It also includes information on the mawk and gawk implementations.
I find this site to be useful (it hasn't let me down yet):

I also find this Cookbook style site quite inspirational:

Hope these help.
