#LONG_DESCRIPTION="The flat assembler is a fast and efficient self-assembling 80x86 assembler for DOS, Windows and Linux operating systems. Currently it supports all 8086-80486/Pentium instructions with MMX, SSE, SSE2, SSE3 and 3DNow! extensions, can produce output in binary, MZ, PE, COFF or ELF format. It includes the powerful but easy to use macroinstruction support and does multiple passes to optimize the instruction codes for size. The flat assembler is self-compilable and the full source code is included."
DESCRIPTION="The flat assembler is a fast and efficient self-assembling multi-platform 80x86 assembler."

#@gen2 devs: it this "legal" for ebuilds? (ie is there anyway to make it do the symlink like: ln -s ${WILL_BE_MY_ROOT}/opt/fasm ${D}usr/bin/fasm).
