+/**
+ * @file backup.cpp
+ * Make a backup of a source file
+ * The current plans are to use two files.
+ *
+ * - A '.unc-backup~' file that contains the original contents
+ * - A '.unc-backup-md5~' file that contains the MD5 over the last output
+ * that uncrustify generated
+ *
+ * The logic goes like this:
+ * 1. If there isn't a .backup-md5 or the md5 over the input file doesn't
+ * match what is in .backup-md5, then copy the source file to .backup.
+ *
+ * 2. Create the output file.
+ *
+ * 3. Calculate the md5 over the output file.
+ * Create the .backup-md5 file.
+ *
+ * This will let you run uncrustify multiple times over the same file without
+ * losing the original file. If you edit the file, then a new backup is made.
+ *
