+/*! @file SimpleGlob.h
+
+ @version 2.8
+
+ @brief A cross-platform file globbing library providing the ability to
+ expand wildcards in command-line arguments to a list of all matching files.
+ It is designed explicitly to be portable to any platform and has been tested on
+ Windows and Linux. See CSimpleGlobTempl for the class definition.
+
+ @section features FEATURES
+
+ - MIT Licence allows free use in all software (including GPL and commercial)
+ - multi-platform (Windows 95/98/ME/NT/2K/XP, Linux, Unix)
+ - supports most of the standard linux glob() options
+ - recognition of a forward paths as equivalent to a backward slash on Windows.
+ e.g. "c:/path/foo*" is equivalent to "c:\path\foo*".
+ - implemented with only a single C++ header file
+ - char, wchar_t and Windows TCHAR in the same program
+ - complete working examples included
+ - compiles cleanly at warning level 4 (Windows/VC.NET 2003), warning level
+ 3 (Windows/VC6) and -Wall (Linux/gcc)
+
+ @section usage USAGE
+
+ The SimpleGlob class is used by following these steps:
+
+ <ol>
+ <li> Include the SimpleGlob.h header file
+
+ <pre>
+ \#include "SimpleGlob.h"
+ </pre>
+
+ <li> Instantiate a CSimpleGlob object supplying the appropriate flags.
+
+ <pre>
+ @link CSimpleGlobTempl CSimpleGlob @endlink glob(FLAGS);
+ </pre>
+
+ <li> Add all file specifications to the glob class.
+
+ <pre>
+ glob.Add("file*");
+ glob.Add(argc, argv);
+ </pre>
+
+ <li> Process all files with File(), Files() and FileCount()
+
+ <pre>
+ for (int n = 0; n < glob.FileCount(); ++n) {
+ ProcessFile(glob.File(n));
+ }
+ </pre>
+
+ </ol>

+/*! @brief The operation of SimpleGlob is fine-tuned via the use of a combination
+ of the following flags.
+
+ The flags may be passed at initialization of the class and used for every
+ filespec added, or alternatively they may optionally be specified in the
+ call to Add() and be different for each filespec.
+
+ @param SG_GLOB_ERR
+ Return upon read error (e.g. directory does not have read permission)
+
+ @param SG_GLOB_MARK
+ Append a slash (backslash in Windows) to every path which corresponds
+ to a directory
+
+ @param SG_GLOB_NOSORT
+ By default, files are returned in sorted into string order. With this
+ flag, no sorting is done. This is not compatible with SG_GLOB_FULLSORT.
+
+ @param SG_GLOB_FULLSORT
+ By default, files are sorted in groups belonging to each filespec that
+ was added. For example if the filespec "b*" was added before the filespec
+ "a*" then the argv array will contain all b* files sorted in order,
+ followed by all a* files sorted in order. If this flag is specified, the
+ entire array will be sorted ignoring the filespec groups.
+
+ @param SG_GLOB_NOCHECK
+ If the pattern doesn't match anything, return the original pattern.
+
+ @param SG_GLOB_TILDE
+ Tilde expansion is carried out (on Unix platforms)
+
+ @param SG_GLOB_ONLYDIR
+ Return only directories which match (not compatible with SG_GLOB_ONLYFILE)
+
+ @param SG_GLOB_ONLYFILE
+ Return only files which match (not compatible with SG_GLOB_ONLYDIR)
+
+ @param SG_GLOB_NODOT
+ Do not return the "." or ".." special directories.
