2.9 combining complete documents into one
2.9.1 combining using manual sectioning
Problem description: I have many standalone Latex documents that I want to compile into documents on
their own, but also I want to combine them into one main document and have the table of contents and other
references work as if all documents were written as one file.
Solution:
Given this example layout
home/main.tex
home/folderA/a.tex
Where main.tex and a.tex are self contained Latex files, each with its own title, table of contents and can
include local resources such as images and listings.
Add the package \usepackage{standalone} in main.tex to strip all the preamble from the included latex
files. Also add it to each child document, so that each child document can be compiled as standalone as well.
To use the above, make sure the master document at the top level includes all packages included by all the
children.
Setup main.tex
