I have written and submitted a lectures series in mathematics in arXiv, arXiv:1211.3404. Its format is book, but I have some difficulties with it. For example for page numbering, indexing, etc. I am going to extend my lecture notes in the form of a relatively long book, so I need to choose a better template for my work.
I am looking for an easy to use and perfect book template in Latex. I need a template that allows indexing, adding appendices, different page numbering for introduction and content, different numbering for exercises.
It is also favorable if the template (preferably) does not use so many user packages.
