the underlying revision storage object
A revlog consists of two parts, an index and the revision data.
The index is a file with a fixed record size containing
information on each revision, including its nodeid (hash), the
nodeids of its parents, the position and offset of its data within
the data file, and the revision it's based on. Finally, each entry
contains a linkrev entry that can serve as a pointer to external
data.
The revision data itself is a linear collection of data chunks.
Each chunk represents a revision and is usually represented as a
delta against the previous chunk. To bound lookup time, runs of
deltas are limited to about 2 times the length of the original
version data. This makes retrieval of a version proportional to
its size, or O(1) relative to the number of revisions.
Both pieces of the revlog are written to in an append-only
fashion, which means we never need to rewrite a file to insert or
remove data, and can use some simple techniques to avoid the need
for locking while reading.

This chapter covers the minimum amount of functionality you'll need to
start using Prawn.
If you are new to Prawn this is the first chapter to read. Once you are
comfortable with the concepts shown here you might want to check the
Basics section of the Graphics, Bounding Box and Text sections.
The examples show:
TEXT
list(
'How to create new pdf documents in every possible way',
'Where the origin for the document coordinates is. What are Bounding '\
'Boxes and how they interact with the origin',
'How the cursor behaves',
'How to start new pages',
'What the base unit for measurement and coordinates is and how to use '\
'other convenient measures',
"How to build custom view objects that use Prawn's DSL"
)
