-# File System Utilities / `inifile` INI File
-
-## Syntax
-
-This directory contains a very simple INI file parser. An INI file consists of a
-sequence of lines up to the end of file. A line may be one of the following:
-
-1. A blank line.
-
-2. A comment line. Any line beginning with `;`
-
-3. A section header. Definitions are divided into sections. Each section begins
-   with a line containing the section name enclosed in square brackets. For
-   example, `[section1]`. The left bracket must be the first character on the
-   line. Section names are case insensitive, i.e., `SECTION1` and `Section1`
-   refer to the same section.
-
-4. Variable assignments. A variable assignment is a variable name followed by
-   the `=` sign and then the value of the variable. For example, `A=B`: `A` is
-   the variable name; `B` is the variable value. All variables following the
-   section header belong in the section.
-
-   Variable names may be preceded with white space. Whitespace is not permitted
-   before the `=` sign. Variable names are case insensitive, i.e., `A` and `a`
-   refer to the same variable name.
-
-   Variable values may be numeric (any base) or a string. The case of string
-   arguments is preserved.
-
-## Programming Interfaces
-
-See `apps/include/fsutils/inifile.h` for interfaces supported by the INI file
-parser.
-
-## Test Program
-
-Below is a simple test program:
-
-```c
-int main(int argc, char *argv[])
-{
-  INIHANDLE handle;
-  FILE *stream;
-  FAR char *ptr;
-  long value;
-
-  stream = fopen("/tmp/file.ini", "w");
-  fprintf(stream, "; Test INI file\n");
-  fprintf(stream, "[section1]\n");
-  fprintf(stream, "  VAR1=1\n");
-  fprintf(stream, "  VAR2=2\n");
-  fprintf(stream, "  VAR3=3\n");
-  fprintf(stream, "\n");
-  fprintf(stream, "[section2]\n");
-  fprintf(stream, "  VAR4=4\n");
-  fprintf(stream, "  VAR5=5\n");
-  fprintf(stream,   "VAR6=6\n");
-  fprintf(stream, "\n");
-  fclose(stream);
-
-  handle = inifile_initialize("/tmp/file.ini");
-
-  ptr = inifile_read_string(handle, "section2", "VAR5", "OOPS");
-  printf("Section: %s Variable: %s String: %s\n", "section2", "VAR5", ptr);
-  inifile_free_string(ptr);
-
-  ptr = inifile_read_string(handle, "section1", "VAR2", "OOPS");
-  printf("Section: %s Variable: %s String: %s\n", "section1", "VAR2", ptr);
-  inifile_free_string(ptr);
-
-  ptr = inifile_read_string(handle, "section3", "VAR3", "OOPS");
-  printf("Section: %s Variable: %s String: %s\n", "section3", "VAR3", ptr);
-  inifile_free_string(ptr);
-
-  ptr = inifile_read_string(handle, "section1", "VAR3", "OOPS");
-  printf("Section: %s Variable: %s String: %s\n", "section1", "VAR3", ptr);
-  inifile_free_string(ptr);
-
-  ptr = inifile_read_string(handle, "section1", "VAR1", "OOPS");
-  printf("Section: %s Variable: %s String: %s\n", "section1", "VAR1", ptr);
-  inifile_free_string(ptr);
-
-  ptr = inifile_read_string(handle, "section1", "VAR42", "OOPS");
-  printf("Section: %s Variable: %s String: %s\n", "section1", "VAR42", ptr);
-  inifile_free_string(ptr);
-
-  ptr = inifile_read_string(handle, "section2", "VAR6", "OOPS");
-  printf("Section: %s Variable: %s String: %s\n", "section2", "VAR6", ptr);
-  inifile_free_string(ptr);
-
-  ptr = inifile_read_string(handle, "section2", "VAR4", "OOPS");
-  printf("Section: %s Variable: %s String: %s\n", "section2", "VAR4", ptr);
-  inifile_free_string(ptr);
-
-  value = inifile_read_integer(handle, "section1", "VAR3", 0);
-  printf("Section: %s Variable: %s Value: %ld\n", "section1", "VAR3", value);
-
-  value = inifile_read_integer(handle, "section3", "VAR3", 0);
-  printf("Section: %s Variable: %s String: %ld\n", "section3", "VAR3", value);
-
-  value = inifile_read_integer(handle, "section1", "VAR1", 0);
-  printf("Section: %s Variable: %s Value: %ld\n", "section1", "VAR1", value);
-
-  value = inifile_read_integer(handle, "section2", "VAR5", 0);
-  printf("Section: %s Variable: %s Value: %ld\n", "section2", "VAR5", value);
-
-  value = inifile_read_integer(handle, "section2", "VAR6", 0);
-  printf("Section: %s Variable: %s Value: %ld\n", "section2", "VAR6", value);
-
-  value = inifile_read_integer(handle, "section1", "VAR42", 0);
-  printf("Section: %s Variable: %s String: %ld\n", "section1", "VAR42", value);
-
-  value = inifile_read_integer(handle, "section1", "VAR2", 0);
-  printf("Section: %s Variable: %s Value: %ld\n", "section1", "VAR2", value);
-
-  value = inifile_read_integer(handle, "section2", "VAR4", 0);
-  printf("Section: %s Variable: %s Value: %ld\n", "section2", "VAR4", value);
-
-  inifile_uninitialize(handle);
-  return 0;
