 /**
-Parser for aws credentials.
+The .aws/config and .aws/credentials files
+are in INI format (https://en.wikipedia.org/wiki/INI_file).
+This format is not well defined, so the grammar used
+here is restrictive. Here, the term "profile" is the same
+as the INI term "section".
+
+The grammar used is as follows:
 
 Grammar:
 
-credsfile: profilelist ;
+inifile: profilelist ;
 profilelist: profile | profilelist profile ;
-profile: '[' profilename ']'
-	entries ;
+profile: '[' profilename ']' EOL entries ;
 entries: empty | entries entry ;
-entry:  WORD = WORD ;
+entry:  WORD = WORD EOL ;
 profilename: WORD ;
 Lexical:
 WORD    sequence of printable characters - [ \[\]=]+
+EOL	'\n' | ';'
+
+Note:
+1. The semicolon at beginning of a line signals a comment.
+2. # comments are not allowed
+3. Duplicate profiles or keys are ignored.
+4. Escape characters are not supported.
