Miniaim

miniaim is a minimalist AIM client using the TOC2 protocol for windows written in C++ by Jon Honeycutt. To conserve executable size, miniaim is packed with the UPX executable packer and uses the Win32 API directly without wrappers. The resulting program fits in 63.5 KB of disk space.

miniaim's small feature-set includes:
*minimizing to tray
*tabbed interface with middle click close
*single executable (no installation needed), with optional OTR library, naturally portable
*option to use your formatting for incoming messages
*support for the Off-the-Record Messaging encryption library
*ability to receive files, with or without using the AOL file transfer proxy
*option to log conversations in html or plain text
*saving settings to a tiny external file (miniaim.ini)
*graphical smilies (with option to disable them)
