 Typos and bug fixes: Typos and bug fixes:
  
-  * no fixes of note +  * bgrep was giving the address of the last byte matched of a pattern, vs. the address of the start of the matched pattern (the intended action). This has been corrected, and **bgrep** has been updated. (20150322) 
 +    * This should not change anything, save for saving you an additional calculation to determine the start of the packet. 
 +  * My aforementioned fix did not work, reverted **bgrep** to original version (20150324) 
 +  * Implemented new fix: **bgrep** should now be correctly reporting the starting address of the matched pattern -- no change on your part, just start using it (and be aware that the address represents the start of the pattern, and not the end) (20150330)

 Continuing our "1337 haxxing" series of projects, we've found considerable conceptual self-imposed roadblocks blocking our employment of otherwise simple computing properties (that data is a series of bytes, and ultimately, that **everything is a file**). Continuing our "1337 haxxing" series of projects, we've found considerable conceptual self-imposed roadblocks blocking our employment of otherwise simple computing properties (that data is a series of bytes, and ultimately, that **everything is a file**).

 Successful completion will result in the following criteria being met: Successful completion will result in the following criteria being met:
  
-  * Resulting file with proper settings should enable you to run **urev** tool. +  * When all is said and done, you will submit: 
-  * You have completed all weekly exercises (96, I think) before the deadline, being mindful of the intentionally-paced nature of urev. +    * **udr2.text**, containing the answers/responses to all the above questions (including commands used to pull off the project)
-    * Bonus opportunity: while still performing a minimum of 3 distict **urev** sessions, how could you get around the urev-imposed time limit? (Without copying/changing urev). +
-  * When all is said and done, you will submit 3 files: +
-    * **udr1.text** +
-      * Append the dd line(s) as well as any other command lines needed to extract and properly re-orient the file. Also be sure to indicate what is in the file you found (content, not just type of data). +
-    * your bash script enabling the processing of data.file to produce gizmo +
-      * Be sure to include comments indicating the reasoning behind actions taken +
-    * Your extracted/processed **gizmo** file +
