+TOML in c99; v1.0 compliant.
+
+If you are looking for a C++ library, you might try this wrapper: [https://github.com/cktan/tomlcpp](https://github.com/cktan/tomlcpp).
+
+* Compatible with [TOML v1.0.0](https://toml.io/en/v1.0.0).
+* Tested with multiple test suites, including
+[toml-lang/toml-test](https://github.com/toml-lang/toml-test) and
+[iarna/toml-spec-tests](https://github.com/iarna/toml-spec-tests).
+* Provides very simple and intuitive interface.
+
+
+## Usage
+
+Please see the `toml.h` file for details. The following is a simple example that
+parses this config file:
+
+```toml
+[server]
+	host = "www.example.com"
+	port = [ 8080, 8181, 8282 ]
+```
+
+These are the usual steps for getting values from a file:
+
+1. Parse the TOML file.
+2. Traverse and locate a table in TOML.
+3. Extract values from the table.
+4. Free up allocated memory.
+
+Below is an example of parsing the values from the example table.
+
+```c
+#include <stdio.h>
+#include <string.h>
+#include <errno.h>
+#include <stdlib.h>
+#include "toml.h"
+
+static void error(const char* msg, const char* msg1)
+{
+    fprintf(stderr, "ERROR: %s%s\n", msg, msg1?msg1:"");
+    exit(1);
+}
+
+
+int main()
+{
+    FILE* fp;
+    char errbuf[200];
+
+    // 1. Read and parse toml file
+    fp = fopen("sample.toml", "r");
+    if (!fp) {
+        error("cannot open sample.toml - ", strerror(errno));
+    }
+
+    toml_table_t* conf = toml_parse_file(fp, errbuf, sizeof(errbuf));
+    fclose(fp);
+
+    if (!conf) {
+        error("cannot parse - ", errbuf);
+    }
+
+    // 2. Traverse to a table.
+    toml_table_t* server = toml_table_in(conf, "server");
+    if (!server) {
+        error("missing [server]", "");
+    }
+
+    // 3. Extract values
+    toml_datum_t host = toml_string_in(server, "host");
+    if (!host.ok) {
+        error("cannot read server.host", "");
+    }
+
+    toml_array_t* portarray = toml_array_in(server, "port");
+    if (!portarray) {
+        error("cannot read server.port", "");
+    }
+
+    printf("host: %s\n", host.u.s);
+    printf("port: ");
+    for (int i = 0; ; i++) {
+        toml_datum_t port = toml_int_at(portarray, i);
+        if (!port.ok) break;
+        printf("%d ", (int)port.u.i);
+    }
+    printf("\n");
+
+    // 4. Free memory
+    free(host.u.s);
+    toml_free(conf);
+    return 0;
+}
+```
+
+#### Accessing Table Content
+
+TOML tables are dictionaries where lookups are done using string keys. In
+general, all access functions on tables are named `toml_*_in(...)`.
+
+In the normal case, you know the key and its content type, and retrievals can be done
+using one of these functions:
+```c
+toml_string_in(tab, key);
+toml_bool_in(tab, key);
+toml_int_in(tab, key);
+toml_double_in(tab, key);
+toml_timestamp_in(tab, key);
+toml_table_in(tab, key);
+toml_array_in(tab, key);
+```
+
+You can also interrogate the keys in a table using an integer index:
+```c
+toml_table_t* tab = toml_parse_file(...);
+for (int i = 0; ; i++) {
+    const char* key = toml_key_in(tab, i);
+    if (!key) break;
+    printf("key %d: %s\n", i, key);
+}
+```
+
+#### Accessing Array Content
+
+TOML arrays can be deref-ed using integer indices. In general, all access methods on arrays are named `toml_*_at()`.
+
+To obtain the size of an array:
+```c
+int size = toml_array_nelem(arr);
+```
+
+To obtain the content of an array, use a valid index and call one of these functions:
+```c
+toml_string_at(arr, idx);
+toml_bool_at(arr, idx);
+toml_int_at(arr, idx);
+toml_double_at(arr, idx);
+toml_timestamp_at(arr, idx);
+toml_table_at(arr, idx);
+toml_array_at(arr, idx);
+```
+
+#### toml_datum_t
+
+Some `toml_*_at` and `toml_*_in` functions return a toml_datum_t
+structure. The `ok` flag in the structure indicates if the function
+call was successful. If so, you may proceed to read the value
+corresponding to the type of the content.
+
+For example:
+```
+toml_datum_t host = toml_string_in(tab, "host");
+if (host.ok) {
+	printf("host: %s\n", host.u.s);
+	free(host.u.s);   /* FREE applies to string and timestamp types only */
+}
+```
+
+** IMPORTANT: if the accessed value is a string or a timestamp, you must call `free(datum.u.s)` or `free(datum.u.ts)` respectively after usage. **
+
+## Building and installing
+
+A normal *make* suffices. You can also simply include the
+`toml.c` and `toml.h` files in your project.
+
+Invoking `make install` will install the header and library files into
+/usr/local/{include,lib}.
+
+Alternatively, specify `make install prefix=/a/file/path` to install into
+/a/file/path/{include,lib}.
+
+## Testing
+
+To test against the standard test set provided by toml-lang/toml-test:
+
+```sh
+% make
+% cd test1
+% bash build.sh   # do this once
+% bash run.sh     # this will run the test suite
+```
+
+
+To test against the standard test set provided by iarna/toml:
+
+```sh
+% make
+% cd test2
+% bash build.sh   # do this once
+% bash run.sh     # this will run the test suite
+```
