-// dear imgui
-// (binary_to_compressed_c.cpp)
-// Helper tool to turn a file into a C array, if you want to embed font data in your source code.
-
-// The data is first compressed with stb_compress() to reduce source code size,
-// then encoded in Base85 to fit in a string so we can fit roughly 4 bytes of compressed data into 5 bytes of source code (suggested by @mmalex)
-// (If we used 32-bit constants it would require take 11 bytes of source code to encode 4 bytes, and be endianness dependent)
-// Note that even with compression, the output array is likely to be bigger than the binary file..
-// Load compressed TTF fonts with ImGui::GetIO().Fonts->AddFontFromMemoryCompressedTTF()
-
-// Build with, e.g:
-//   # cl.exe binary_to_compressed_c.cpp
-//   # g++ binary_to_compressed_c.cpp
-//   # clang++ binary_to_compressed_c.cpp
-// You can also find a precompiled Windows binary in the binary/demo package available from https://github.com/ocornut/imgui
-
-// Usage:
-//   binary_to_compressed_c.exe [-base85] [-nocompress] [-nostatic] <inputfile> <symbolname>
-// Usage example:
-//   # binary_to_compressed_c.exe myfont.ttf MyFont > myfont.cpp
-//   # binary_to_compressed_c.exe -base85 myfont.ttf MyFont > myfont.cpp
