+# vxorg
+
+vxheaven organizer (converts it from a flat hierarchy of ~270k+ files to a neat tree). Originally written in python, I rewrote it in C++ for performance reasons.
+
+# History
+
+- 2018: I wrote a really shoddy attempt at doing organization in Bash. It sucked because I wasn't taking care of many idosyncracies about sample naming.
+    - It also was very primitive and slow, since it would continually spawn `mv` processes just to move files. (same for `mkdir` too, but that is less of a concern since it's done less)
+- 2023: I wrote a new script in Python. It was "better" but still didn't work 
+    - I actually made the same mistake and tried to write in Bash again, but even Python was worlds faster, so I rewrote it in python
+- October 21, 2024: I decided to start rewriting the Python script I wrote to parse into a N-ary tree for memory savings while still allowing memoization. (and be modular instead of one blob)
+    - Later in the day, as an experiment, I rewrote the parsing algorithm (fixing a bug in the process) in C++. It was 100x faster, so I committed to a rewrite in C++
+
+# Building
+
+`make`
+
+# Usage
+
+- Generate a list of samples.
+    - `tar tf xxx/viruses-2010-05-18.tar.bz2 | sed 's/\.\///g' | awk NF | sort > list` is one option. Not the best but it's (basically) what I did
+- Run with `./vxorg list src/ dest/`
+    - `dest/` will be created if it does not exist.
+    - It will show a progress bar as it completes.
