As described in Custom VB6 Language Replacement, gmStudio allows users to modify the files that control how the tool recognizes, interprets, and authors code. This is done by configuring the tool to use a project-specific copy of the default metalanguage files. However, product updates frequently include changes to the default metalanguage files, so care must be taken to make your modified files remain compatible with the system defaults. The Configuration Form facilitates this by helping you compare and merge the system default files with your project-specific files. This can also be helpful if you want to review changes or remove a change from your project specific files.

It is a best practice to keep your migration solution, including all configuration files and the installers for gmStudio, under version control.
