{standalone} is about questions regarding the standalone bundle that allows users to easily place picture environments or other material in separate source files and compile these on their own or as part of a main document.
standalone – Compile TeX pictures stand-alone or as part of a document
A class and package is provided which allows TeX pictures or other TeX code to be compiled standalone or as part of a main document. Special support for pictures with beamer overlays is also provided.
The package is used in the main document and skips extra preambles in sub-files. The class may be used to simplify the preamble in sub-files. The behaviour in standalone mode may adjusted using a configuration file standalone.cfg to redefine the standalone environment.
