+xvi (tiny but full-featured vi clone)
+
+Xvi is a portable multi-window version of the UNIX editor 'vi', derived
+from "STEVIE" in the 1980s. The program was originally developed for the
+Atari ST, but has been ported to many platforms. In spite of its name,
+there is, as yet, no X-Windows-specific version of it.
+
+It uses text windows separated by horizontal status lines on character
+mode displays and the windows may represent different files being edited,
+or different views on to the same file.
+
+Two environment variables are supported:
+
+  OPT=-O2     - Build with regular optimization level (default is -Os).
+  STATIC=yes  - Build the xvi binary statically linked.
+
+See README_SBo.txt for more details.

+The xvi binary is 2/3 the size of Slackware's nano binary, or 1/4 the
+size of elvis, or 1/20 the size of vim. It's also approximately 1/2 the
+size of ex-vi. This isn't quite a fair comparison as xvi is built with
+-Os (optimize for size) by default. If you want to use -O2 like other
+SlackBuilds do, set OPT=-O2 in the environment. xvi will be 25% larger,
+but it'll still be 15% smaller than nano.
+
+Since xvi is a standalone binary (doesn't rely on support files, like
+vim's /usr/share/vim/*), it makes a good 'system rescue' editor. If
+built statically, it makes an even better rescue editor. To do this,
+set STATIC=yes in the environment. In this case, xvi will be installed
+to /bin, since it might be needed to recover from a "can't mount /usr"
+situation. Note that xvi's internal help will not be available, if /usr
+isn't mounted.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
