o Add two new Script scan phases:
Script Pre-scanning phase: before any Nmap scan operation, activated by the new "prerule".
Script Post-scanning phase: after all Nmap scan operations, activated by the new "postrule".
o New environment variables:
SCRIPT_PATH
SCRIPT_NAME
SCRIPT_TYPE: the type of the rule that activated the script.
with modifications from [2].
** Short description from [1] **
I have created a patch to NSE that replaces runlevels with a table of
dependencies that clearly outlines what other scripts the script
depends on. The table is of the form:
dependences = {"script1", script2", ...}
Runlevels become an internal representation of the order of scripts
that are generated by the dependencies. Dependencies only enforce
an execution order and not a requirement for execution.

messages. Instead of handling an error nicely, it caused a format string
error of its own:
./nselib/stdnse.lua:61: bad argument #3 to 'format' (string expected, got nil)
It seems that a deadlock happens immediately after one of these errors
occurs. This change doesn't fix the deadlock but allows the underlying
error message to be printed.
I made every script follow a standard form: it starts with the id, followed by
the description. The description is contained in [[ ]] delimiters. The
description is in the global description variable, not in a LuaDoc comment.
Other LuaDoc information such as @args and @usage follows the description in a
comment.
The first paragraph of each description is a a short summary of what the script
does. More detailed information, if any, is given in following paragraphs.
I also improved some wording and formatting in a few cases.
