+# i
+
+A minimalist system information utility with a hex dump aesthetic.
+
+
+
+## Description
+
+"i" is a lightweight terminal-based system information tool that displays
+system stats in an immersive hex editor style interface. It shows real-time
+information about your system including time, uptime, memory usage, CPU usage,
+network status, battery status, and VPN connectivity.
+
+## Features
+
+* Real-time system monitoring
+* Hex dump background (cause why not)
+* Battery status detection
+* Network interface monitoring
+* VPN status detection
+* Power controls (reboot/shutdown)
+* Adaptive terminal width layout
+* Small, hackable Codebase
+
+## Requirements
+
+* C99 compiler
+* termbox2 library
+* POSIX-compliant system
+
+## Installation
+
+Edit config.mk to match your local setup (i is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install sysinfo
+(if necessary as root):
+
+ make clean install
+
+## Configuration
+
+The configuration of i is done by creating a custom config.h
+and (re)compiling the source code.
+
+## Controls
+
+* `q` or `ESC` - Quit
+* `r` - Reboot system
+* `s` - Shutdown system
+
+## Credits
+
+Uses termbox2 for terminal UI rendering.

+ *
+ * TB_OPT_PRINTF_BUF: Write buffer size for printf operations. Represents the
+ * largest string that can be sent in one call to
+ * `tb_print*` and `tb_send*` functions. Defaults to 4096.
+ *
+ * TB_OPT_READ_BUF: Read buffer size for tty reads. Defaults to 64.

+ * TB_OPT_LIBC_WCHAR: If set, use libc's `wcwidth(3)`, `iswprint(3)`, etc

+ * `TB_BLUE`, `TB_MAGENTA`, `TB_CYAN`, `TB_WHITE`
+ *
+ * Plus `TB_DEFAULT` which skips sending a color code (i.e., uses the

+ * As in all modes, the value 0 is interpreted as `TB_DEFAULT` for

+ * `fg` only and are ignored as `bg` attributes.
+ *
+ * Example usage: `tb_set_cell(x, y, '@', TB_BLACK | TB_BOLD, TB_RED)`
+ *
+ * 2. `TB_OUTPUT_256` => [0..255] + `TB_HI_BLACK`
+ *
+ * In this mode you get 256 distinct colors (plus default):
+ * 0x00 (1): `TB_DEFAULT`
+ * `TB_HI_BLACK` (1): `TB_BLACK` in `TB_OUTPUT_NORMAL`
+ * 0x01..0x07 (7): the next 7 colors as in `TB_OUTPUT_NORMAL`
+ * 0x08..0x0f (8): bright versions of the above
+ * 0x10..0xe7 (216): 216 different colors
+ * 0xe8..0xff (24): 24 different shades of gray
+ *
+ * All `TB_*` style attributes except `TB_BRIGHT` may be bitwise OR'd as in
+ * `TB_OUTPUT_NORMAL`.
+ *
+ * Note `TB_HI_BLACK` must be used for black, as 0x00 represents default.
+ *

+ *
+ * This mode supports the 216-color range of `TB_OUTPUT_256` only, but you
+ * don't need to provide an offset:
+ * 0x00 (1): `TB_DEFAULT`
+ * 0x01..0xd8 (216): 216 different colors
+ *
+ * 4. `TB_OUTPUT_GRAYSCALE` => [0..24]
+ *
+ * This mode supports the 24-color range of `TB_OUTPUT_256` only, but you
+ * don't need to provide an offset:
+ * 0x00 (1): `TB_DEFAULT`
+ * 0x01..0x18 (24): 24 different shades of gray
+ *
+ * 5. `TB_OUTPUT_TRUECOLOR` => [0x000000..0xffffff] + `TB_HI_BLACK`
+ *
+ * This mode provides 24-bit color on supported terminals. The format is
+ * 0xRRGGBB.
+ *
+ * All `TB_*` style attributes except `TB_BRIGHT` may be bitwise OR'd as in
+ * `TB_OUTPUT_NORMAL`.
+ *
+ * Note `TB_HI_BLACK` must be used for black, as 0x000000 represents default.
+ *
+ * To use the terminal default color (i.e., to not send an escape code), pass
+ * `TB_DEFAULT`. For convenience, the value 0 is interpreted as `TB_DEFAULT` in
+ * all modes.
+ *
+ * Note, cell attributes persist after switching output modes. Any translation
+ * between, for example, `TB_OUTPUT_NORMAL`'s `TB_RED` and
+ * `TB_OUTPUT_TRUECOLOR`'s 0xff0000 must be performed by the caller. Also note
+ * that cells previously rendered in one mode may persist unchanged until the
+ * front buffer is cleared (such as after a resize event) at which point it will
+ * be re-interpreted and flushed according to the current mode. Callers may
+ * invoke `tb_invalidate` if it is desirable to immediately re-interpret and
+ * flush the entire screen according to the current mode.
+ *
+ * Note, not all terminals support all output modes, especially beyond
+ * `TB_OUTPUT_NORMAL`. There is also no very reliable way to determine color
+ * support dynamically. If portability is desired, callers are recommended to
+ * use `TB_OUTPUT_NORMAL` or make output mode end-user configurable. The same
