+This file summarizes the C style used for Jim.

+
+-----------
+INDENTATION
+-----------
+
+Indentation is 4 spaces, no smart-tabs are used (i.e.
+two indentation steps of 4 spaces will not be converted
+into a real tab, but 8 spaces).
+
+---------------
+FUNCTIONS NAMES
+---------------
+
+Functions names of exported functions are in the form:
+
+Jim_ExportedFunctionName()
+
+The prefix is "Jim_", every word composing the function name
+is capitalized.
+
+Not exported functions that are of general interest for the Jim
+core, like JimFreeInterp() are capitalized the same way, but the
+prefix used for this functions is "Jim" instead of "Jim_".
+Another example is:
+
+JimNotExportedFunction()
+
+Not exported functions that are not general, like functions
+implementing hashtables or Jim objects methods can be named
+in any prefix as long as capitalization rules are followed,
+like in:
+
+ListSetIndex()
+
+---------------
+VARIABLES NAMES
+---------------
+
+Global variables follow the same names convention of functions.
+
+Local variables have usually short names. A counter is just 'i', or 'j',
+or something like this. When a longer name is required, composed of
+more words, capitalization is used, but the first word starts in
+lowcase:
+
+thisIsALogVarName
+
+----
+GOTO
+----
+
+Goto is allowed every time it makes the code cleaner, like in complex
+functions that need to handle exceptions, there is often an "err" label
+at the end of the function where allocated resources are freed before to exit
+with an error. Goto is also used in order to escape multiple nested loops.
+
+----------
+C FEATURES
+----------
+
+Only C89 ANSI C is allowed. C99 features can't be used currently.
+GCC extensions are not allowed.
