The snapshot package helps the owner of a LaTeX document obtain
|
||
|
|
a list of the external dependencies of the document, in a form
|
||
|
|
that can be embedded at the top of the document. It provides a
|
||
|
|
snapshot of the current processing context of the document,
|
||
|
|
insofar as it can be determined from inside LaTeX. If a
|
||
|
|
document contains such a dependency list, then it becomes
|
||
|
|
possible to arrange that the document be processed always with
|
||
|
|
the same versions of everything, in order to ensure the same
|
||
|
|
output. This could be useful for someone wanting to keep a
|
||
|
|
LaTeX document on hand and consistently reproduce an identical
|
||
|
|
DVI file from it, on the fly; or for someone wanting to shield
|
||
|
|
a document during the final stages of its production cycle from
|
||
|
|
unexpected side effects of routine upgrades to the TeX system.
