add some thread samples
epub.py - some books, e.g. Big Nerd Range series, they have more complicated structure in tag h1/h2/h3.., so we need to extract text only to create epub index
epub.py - export index.html/findex.html directly
when building epub files, so OEBPS can be directly used as web source, index2frame is not necessary
epub2html.py - merge the functions of original files:
epub2html.py    extract epub to a folder, only OEBPS are extracts
epub2index.py   build index.html from toc.ncx (bug: index.html is overwritten)
index2frame.py  convert previous index into frame-based (backup index.html if applicable)
delete epub2index.py index2frame.py
gui/xpy.py - remove test code
xcb - using xcb X11 libs, both c and xpyb
xt.py - build a simple toolkit based on xcb. The xt can be used for simple and quick access X11 protocol in developing of eod/etx
gtkmm-hello.cpp: simple gtkmm demo
add more distills: this time json4epub.txt lang.txt xcb.txt.
Before these, we have already beautifulsoup.txt debug.txt git.html lxml.txt python.txt vim.txt
