Release Notes: The -I and -O flags have been added for programs which can use stdin or stdout but expect it to be seekable. -I will buffer stdin into a file before running the command, and -O does a similar thing for stdout.
Release Notes: Addition of pip_latex2html (a wrapper around latex2html), improved documentation, and the temporary-file-handling code uses File::Temp.
Release Notes: Pip is now packaged properly with a Makefile.PL, test suite, and manual pages. A /tmp race condition and other bugs were fixed. The new -b switch specifies a file used for both input and output.
Release Notes: Should work with perl 5.6.
Release Notes: This release adds pip_latex, which lets TeX or LaTeX act as filters.
