-# `mkfs.hefs` – OpenHeFS Filesystem Formatter
-
-`mkfs.hefs` is a command-line utility used to format a block device or disk image with the **High-throughput Extended File System (OpenHeFS)** used by NeKernel. This tool initializes a OpenHeFS volume by writing a boot node and configuring directory and inode index regions, block ranges, and volume metadata.
-
----
-
-## 🛠 Features
-
-- Writes a valid `BootNode` to the specified output device or file.
-- Sets disk size, sector size, and volume label.
-- Supports user-defined ranges for:
-  - Index Node Directory (IND)
-  - Inodes (IN)
-  - Data blocks
-- UTF-8 encoded volume label support.
-- Fully compatible with NeKernel's VFS subsystem.
-
----
-
-## 🧪 Usage
-
-    mkfs.hefs -L <label> -s <sector_size> \
-              -b <ind_start> -e <ind_end> \
-              -bs <block_start> -be <block_end> \
-              -is <in_start> -ie <in_end> \
-              -S <disk_size> -o <output_device>
-

-## 🧾 Arguments
-
-| Option        | Description                                                             |
-|---------------|-------------------------------------------------------------------------|
-| `-L`          | Volume label (UTF-8, internally stored as UTF-16)                       |
-| `-s`          | Sector size (e.g., 512)                                                 |
-| `-b` `-e`     | Start and end addresses for the **Index Node Directory (IND)** region   |
-| `-bs` `-be`   | Start and end addresses for the **Block** data region                   |
-| `-is` `-ie`   | Start and end addresses for the **Inode** region                        |
-| `-S`          | Disk size in **gigabytes**                                              |
-| `-o`          | Path to the output device or image file                                 |
-
-> All address-based inputs (`-b`, `-e`, etc.) must be specified in **hexadecimal** format.
-
----
-
-## 🧷 Notes
-
-- Default sector size is `512` bytes.
-- Default volume name is `"HeFS_VOLUME"`, defined as `kOpenHeFSDefaultVolumeName`.
-- The tool writes a `BootNode` at the beginning of the index node range.
-- A CRC-safe magic signature is embedded for boot and integrity validation.
-- After writing the metadata, the tool flushes and closes the file stream.

-
-## 💻 Example
-
-    mkfs.hefs -L "MyHeFS" -s 512 \
-              -b 0x1000 -e 0x8000 \
-              -bs 0x8000 -be 0x800000 \
-              -is 0x800000 -ie 0xA00000 \
-              -S 128 -o hefs.img
-
-This will create a 128 GiB formatted OpenHeFS image named `hefs.img` with specified region boundaries.
-
----
-
-## 📁 BootNode Structure
-
-The `BootNode` stores key filesystem metadata:
-
-    struct BootNode {
-      char     magic[8];
-      char16_t volumeName[64];
-      uint16_t version;
-      uint16_t diskKind;
-      uint16_t encoding;
-      uint64_t diskSize;
-      uint32_t sectorSize;
-      uint64_t startIND, endIND;
-      uint64_t startIN, endIN;
-      uint64_t startBlock, endBlock;
-      uint64_t indCount;
-      uint16_t diskStatus;
-    };
-
----
-
-## ⚠️ Error Handling
-
-- Prints usage and exits on invalid/missing arguments.
-- Exits with error if the output device cannot be opened or written to.
-- Checks for zero sector size or disk size to prevent invalid formatting.
