+.SH NAME
+.B pylint
+\- python code static checker
+
+.SH SYNOPSIS
+.B pylint
+[
+.I OPTIONS
+] [
+.I <arguments>
+]
+
+.SH DESCRIPTION
+.B pylint
+is a Python source code analyzer which looks for programming
+errors, helps enforcing a coding standard and sniffs for some code
+smells (as defined in Martin Fowler's Refactoring book)
+
+Pylint can be seen as another PyChecker since nearly all tests you
+can do with PyChecker can also be done with Pylint. However, Pylint
+offers some more features, like checking length of lines of code,
+checking if variable names are well-formed according to your coding
+standard, or checking if declared interfaces are truly implemented,
+and much more.
+
+Additionally, it is possible to write plugins to add your own checks.
+
+.SH OPTIONS
+.IP "--version"
+show program's version number and exit
+.IP "--help, -h"
+show this help message and exit
+
+.SH MASTER

+.IP "--rpython-mode"
+enable the rpython checker which is disabled by default
+.IP "--errors-only, -e"
+In debug mode, checkers without error messages are disabled and for others, only the ERROR messages are displayed, and no reports are done by default
+.IP "--profile=<y_or_n>"
+Profiled execution. [current: %default]
+.IP "--ignore=<file>"
+Add <file or directory> to the black list. It should be a base name, not a path. You may set this option multiple times. [current: %default]

+.IP "--list-msgs"

+.IP "--generate-man"
+Generate pylint's man page.
