If you have to deal with termcap or terminfo, and
especially if you find yourself having to write
or modify a terminal specification, this book is
essential. The seemingly endless forest of
terminal capabilities are broken down into
logical groups. Were I to make one suggestion
for a fourth edition, it would be that it include
the capabilities that apparently were adopted
after the third edition was written that control
color settings on terminals and terminal
emulators capable of color.
