+Introduction</a></h2>
+iniParser is a simple C library offering ini file parsing services. The library is pretty small (less than 1500 lines of C) and robust, and does not depend on any other external library to compile. It is written in ANSI C and should compile on most platforms without difficulty.<p>
+<hr>
+<h2><a class="anchor" name="inidef">
+What is an ini file?</a></h2>
+An ini file is an ASCII file describing simple parameters (character strings, integers, floating-point values or booleans) in an explicit format, easy to use and modify for users.<p>
+An ini file is segmented into Sections, declared by the following syntax:<p>
+<div class="fragment"><pre class="fragment">
+ [Section Name]
+ </pre></div><p>
+i.e. the section name enclosed in square brackets, alone on a line. Sections names are allowed to contain any character but square brackets or linefeeds. Slashes (/) are also reserved with this parser for hierarchical sections (see below).<p>
+In any section are zero or more variables, declared with the following syntax:<p>
+<div class="fragment"><pre class="fragment">
+ Key = value ; comment
+ </pre></div><p>
+The key is any string (possibly containing blanks). The value is any character on the right side of the equal sign. Values can be given enclosed with quotes. If no quotes are present, the value is understood as containing all characters between the first and the last non-blank characters. The following declarations are identical:<p>
+<div class="fragment"><pre class="fragment">
+ Hello = "this is a long string value" ; comment
+ Hello = this is a long string value ; comment
+ </pre></div><p>
+The semicolon and comment at the end of the line are optional. If there is a comment, it starts from the first character after the semicolon up to the end of the line.<p>
+Multi-line values can be provided by ending the line with a backslash (\).<p>
+<div class="fragment"><pre class="fragment">
+ Multiple = Line 1 \
+ Line 2 \
+ Line 3 \
+ Line 4 ; comment
+ </pre></div><p>
+This would yield: "multiple" <- "Line1 Line2 Line3 Line4"<p>
+Comments in an ini file are:<p>
+<ul>
+<li>Lines starting with a hash sign</li><li>Blank lines (only blanks or tabs)</li><li>Comments given on value lines after the semicolon (if present)</li></ul>
+<p>

+<h2><a class="anchor" name="install">
+Compiling/installing the library</a></h2>
+Edit the Makefile to indicate the C compiler you want to use, the options to provide to compile ANSI C, and possibly the options to pass to the <code>ar</code> program on your machine to build a library (.a) from a set of object (.o) files.<p>
+Defaults are set for the gcc compiler and the standard ar library builder.<p>
+Type 'make', that should do it.<p>
+To use the library in your programs, add the following line on top of your module:<p>
+<div class="fragment"><pre class="fragment"><span class="preprocessor"> #include "<a class="code" href="iniparser_8h.html" title="Parser for ini files.">iniparser.h</a>"</span>
+</pre></div><p>
+And link your program with the iniparser library by adding <code>-liniparser.a</code> to the compile line.<p>
+See the file test/initest.c for an example.<p>
+<hr>
+<h2><a class="anchor" name="reference">
+Library reference</a></h2>
+The library is completely documented in its header file. On-line documentation has been generated and can be consulted here:<p>
+<ul>
+<li><a class="el" href="iniparser_8h.html" title="Parser for ini files.">iniparser.h</a></li></ul>
+<p>
+<hr>
+<h2><a class="anchor" name="usage">
+Using the parser</a></h2>
+Comments are discarded by the parser. Then sections are identified, and in each section a new entry is created for every keyword found. The keywords are stored with the following syntax:<p>
+<div class="fragment"><pre class="fragment">
+ [Section]
+ Keyword = value ; comment
+ </pre></div><p>
+is converted to the following key pair:<p>
+<div class="fragment"><pre class="fragment">
+ ("section:keyword", "value")
+ </pre></div><p>
+This means that if you want to retrieve the value that was stored in the section called <code>Pizza</code>, in the keyword <code>Cheese</code>, you would make a request to the dictionary for <code>"pizza:cheese"</code>. All section and keyword names are converted to lowercase before storage in the structure. The value side is conserved as it has been parsed, though.<p>
+Section names are also stored in the structure. They are stored using as key the section name, and a NULL associated value. They can be queried through <a class="el" href="iniparser_8h.html#3d67c98bbc0cb5239f024ad54bdc63f1" title="Finds out if a given entry exists in a dictionary.">iniparser_find_entry()</a>.<p>
+To launch the parser, use the function called <a class="el" href="iniparser_8h.html#b0be559bfb769224b3f1b75e26242a67" title="Parse an ini file and return an allocated dictionary object.">iniparser_load()</a>, which takes an input file name and returns a newly allocated <em>dictionary</em> structure. This latter object should remain opaque to the user and only accessed through the following accessor functions:<p>
+<ul>
+<li><a class="el" href="iniparser_8h.html#7894f8480e1f254d4a1b4a31bdc51b46" title="Get the string associated to a key.">iniparser_getstring()</a></li><li><a class="el" href="iniparser_8h.html#694eb1110f4200db8648820a0bb405fa" title="Get the string associated to a key, convert to an int.">iniparser_getint()</a></li><li><a class="el" href="iniparser_8h.html#480d35322f1252344cf2246ac21ee559" title="Get the string associated to a key, convert to a double.">iniparser_getdouble()</a></li><li><a class="el" href="iniparser_8h.html#eb93c13fcbb75efaa396f53bfd73ff4d" title="Get the string associated to a key, convert to a boolean.">iniparser_getboolean()</a></li></ul>
+<p>
+Finally, discard this structure using <a class="el" href="iniparser_8h.html#90549ee518523921886b74454ff872eb" title="Free all memory associated to an ini dictionary.">iniparser_freedict()</a>.<p>
+All values parsed from the ini file are stored as strings. The accessors are just converting these strings to the requested type on the fly, but you could basically perform this conversion by yourself after having called the string accessor.<p>
+Notice that <a class="el" href="iniparser_8h.html#eb93c13fcbb75efaa396f53bfd73ff4d" title="Get the string associated to a key, convert to a boolean.">iniparser_getboolean()</a> will return an integer (0 or 1), trying to make sense of what was found in the file. Strings starting with "y", "Y", "t", "T" or "1" are considered true values (return 1), strings starting with "n", "N", "f", "F", "0" are considered false (return 0). This allows some flexibility in handling of boolean answers.<p>
+If you want to add extra information into the structure that was not present in the ini file, you can use <a class="el" href="iniparser_8h.html#89d37d24721b68a3702f40505bd36985" title="Set an entry in a dictionary.">iniparser_setstring()</a> to insert a string.<p>

+<h2><a class="anchor" name="implementation">
+A word about the implementation</a></h2>
+The dictionary structure is a pretty simple dictionary implementation which might find some uses in other applications. If you are curious, look into the source.<p>
