* Modifications:
* --------------------------------------------------------------------------
* $Log: ncbienv.h,v $
* Revision 6.4  2003/06/06 15:01:03  rsmith
* fixed ProgramPath for OS Darwin & Mac, Added IsApplicationPackage for Darwin. ProgramPath on Darwin now returns the seen application not the executable buried in the package.
*
* Revision 6.3  2003/01/29 19:37:14  kans
* added GetOpSysString to return allocated string describing operating system running the program
*
* Revision 6.2  1999/11/29 19:58:50  vakatov
* To parse command-line arguments:
* + ECmdLineQuote, Nlm_ParseCmdLineArguments(), Nlm_FreeCmdLineArguments()
*
* Revision 6.1  1999/02/12 16:01:41  vakatov
* Added a draft version of Nlm_GetEnvParamEx()
* Got rid of the old "PROTO" and "LIBCALL" prototype junk, etc.
*
* Revision 5.1  1996/12/03 21:48:33  vakatov
* Adopted for 32-bit MS-Windows DLLs
*
* Revision 4.1  1995/10/06  15:54:00  epstein
* add CacheAppParam() and FlushAppParam()
*
* 06-14-94  Schuler     Created this file.  These definitions previously
*                       resided in ncbimain.h
* 06-14-94  Schuler     Added some new functions:
*                       GetAppParamBoolean() , SetAppParamBoolean(),
*                       GetAppParamInt2(), SetAppParamInt2(),
*                       GetAppParamInt4(), SetAppParamInt4()
* 06-14-94  Schuler     Added LIBCALL to ProgramPath
