 # SimpleITKSpellChecking

+
+
 A script that automatically spell checks the comments of a code base.
 It is intended to be run on the SimpleITK and ITK code bases.
 
 Here is how it is typically run:
 
     python codespell.py --exclude Ancillary $SIMPLEITK_SOURCE_DIR/Code
 
-This will recursively find all the '.h' files in a directory, extract
-the C/C++ comments from the code and run a spell checker on them.
-The '--exclude' flag tells the script to ignore any file that has
-'Ancillary' in it's full path name.  This flag will accept any

+The **'--exclude'** flag tells the script to ignore any file that has

 regular expression.
 
-In addition to pyenchant's English dictionary, we use the words in 
-**additional_dictionary.txt**.  These are proper names and technical

-In addition to checking each word against the dictionary, if a word
-fails, we try two additional checks.
+If a word is not found in the dictionaries, we try two additional checks.
 
-First, if the word starts with some know prefix, the prefix is removed 
-and the remaining word is checked.  The prefixes currently checked
-are 'sitk', 'itk', and 'vtk'.  Additional prefixes can be specified
-with the '--prefix' command line argument.

+...used by default are **'sitk'**, **'itk'**, and **'vtk'**.  Additional

-Second, we attempt to split the word by capitalization and check each
-sub-word.  This is an attempt to detect camel-case words such as
-'GetArrayFromImage', which would get split into 'Get', 'Array', 'From',
-and 'Image'.  Camel-case words are very commonly used for code elements.
