/**
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.
