If you write a script, you can send input into it like this:

./somescript < inputfile

The script can accomplish the same thing internally by using:
exec < inputfile

After that line, the script's input is inputfile. It can do the same to output:

exec > somescript.log 2>&1

This send stderr and stdout combined into the file. There is more to it, but this is the basics.

wmc

WMC(1)							      Wine Developers Manual							    WMC(1)

NAME

       wrc - Wine Message Compiler

SYNOPSIS

       wmc [options] [inputfile]

DESCRIPTION

       wmc  compiles  messages	from  inputfile into FormatMessage[AW] compatible format encapsulated in a resourcescript format.  wmc outputs the
       data either in a standard .bin formatted binary file, or can generated inline resource data.

       wmc takes only one inputfile as argument (see BUGS). The inputfile normally has extension .mc. The messages are read from standard input if
       no  inputfile  is given. If the outputfile is not specified with -o, then wmc will write the output to inputfile.{rc,h}.  The outputfile is
       named wmc.tab.{rc,h} if no inputfile was given.

OPTIONS

       -B x   Set output byte-order x={n[ative], l[ittle], b[ig]}. Default is n[ative].

       -c     Set 'custom-bit' in message-code values.

       -d     NON-FUNCTIONAL; Use decimal values in output

       -D     Set debug flag. This results is a parser trace and a lot of extra messages.

       -h     Print an informative usage message.

       -H file
	      Write headerfile to file. Default is inputfile.h.

       -i     Inline messagetable(s). This option skips the generation of all .bin files and writes all output into the .rc file. This encoding is
	      parsable with wrc(1).

       -o file
	      Output to file. Default is inputfile.rc.

       -u     Assume that the inputfile is in unicode.

       -U     Write resource output in unicode formatted messagetable(s).

       -v     Show all supported codepages and languages.

       -V     Print version end exit.

       -W     Enable pedantic warnings.

EXTENSIONS

       The  original  syntax  is  extended to support codepages more smoothly. Normally, codepages are based on the DOS-codepage from the language
       setting. The original syntax only allows the destination codepage to be set. However, this is not enough for non-DOS systems which  do  not
       use unicode source-files.

       A new keyword Codepages is introduced to set both input and output codepages to anything one wants for each language. The syntax is similar
       to the other constructs:

       Codepages '=' '(' language '=' cpin ':' cpout ... ')'

       The language is the numerical language-ID or the alias set with LanguageNames. The input-codepage cpin and output-codepage  cpout  are  the
       numerical codepage-IDs. There can be multiple mapping within the definition and the definition may occur more than once.

AUTHORS

       wmc was written by Bertho A. Stultiens.

BUGS

       The  message  compiler  should be able to have multiple inputfiles and combine them into one outputfile. This would enable the splitting of
       languages into separate files.

       Unicode detection of the input is suboptimal, to say the least. It should recognize byte-order-marks (BOM) and decide what to do.

       Decimal output is completely lacking. Don't know whether it should be implemented because it is a, well, non-informative format change.	It
       is recognized on the commandline for some form of compatibility.

AVAILABILITY

       wmc is part of the wine distribution, which is available through WineHQ, the wine development headquarters, at http://www.winehq.org/.
