IniDiffUtils compares, patches and filters INI files
IniDiffUtils is a package of Perl utilities that compares, patches and filters INI files.
It works much as the GNU diffutils package works, but taking the INI structure of section, key and values into account.
It is derived from Michael Rendell's wonderful and unique Regutils package now maintained here: https://sourceforge.net/projects/regutils/, but originally available here: http://www.cs.mun.ca/~michael/regutils.
IniDiffUtils was separated from the other parts of RegUtils so that INI differencing, filtering and patching could be treated separately from the Windows registry focus of the original package.
