-
-
-This module provides a facility to convert regular expressions from the
-syntax used by the deprecated \module{regex} module to those used by the
-newer \module{re} module.  Because of similarity between the regular
-expression syntax of \code{sed(1)} and \code{emacs(1)} and the
-\module{regex} module, it is also helpful to convert patterns written for
-those tools to \module{re} patterns.
-
-When used as a script, a Python string literal (or any other expression
-evaluating to a string) is read from stdin, and the translated expression is
-written to stdout as a string literal.  Unless stdout is a tty, no trailing
-newline is written to stdout.  This is done so that it can be used with
-Emacs \code{C-U M-|} (shell-command-on-region) which filters the region
-through the shell command.

-The module defines two functions and a handful of constants.
-
-\begin{funcdesc}{convert}{pattern\optional{, syntax=None}}
- Convert a \var{pattern} representing a \module{regex}-stype regular
- expression into a \module{re}-style regular expression.  The optional
- \var{syntax} parameter is a bitwise-or'd set of flags that control what
- constructs are converted.  See below for a description of the various
- constants.
-\end{funcdesc}
-
-\begin{funcdesc}{quote}{s\optional{, quote=None}}
- Convert a string object to a quoted string literal.
-
- This is similar to \function{repr} but will return a "raw" string (r'...'
- or r"...") when the string contains backslashes, instead of doubling all
- backslashes.  The resulting string does not always evaluate to the same
- string as the original; however it will do just the right thing when passed
- into re.compile().
-
- The optional second argument forces the string quote; it must be a single
- character which is a valid Python string quote.  Note that prior to Python
- 2.5 this would not accept triple-quoted string delimiters.
-\end{funcdesc}
-
-\begin{datadesc}{RE_NO_BK_PARENS}
- Suppress paren conversion.  This should be omitted when converting
- \code{sed}-style or \code{emacs}-style regular expressions.
-\end{datadesc}
-
-\begin{datadesc}{RE_NO_BK_VBAR}
- Suppress vertical bar conversion.  This should be omitted when converting
- \code{sed}-style or \code{emacs}-style regular expressions.
-\end{datadesc}
-
-\begin{datadesc}{RE_BK_PLUS_QM}
- Enable conversion of \code{+} and \code{?} characters.  This should be
- added to the \var{syntax} arg of \function{convert} when converting
- \code{sed}-style regular expressions and omitted when converting
- \code{emacs}-style regular expressions.

-
-This module defines a number of functions useful for working with
-regular expressions (see built-in module \refmodule{regex}).
-
-Warning: these functions are not thread-safe.
-
-\strong{Obsolescence note:}
-This module is obsolete as of Python version 1.5; it is still being
-maintained because much existing code still uses it.  All new code in
-need of regular expressions should use the new \refmodule{re} module, which
-supports the more powerful and regular Perl-style regular expressions.
-Existing code should be converted.  The standard library module
-\module{reconvert} helps in converting \refmodule{regex} style regular
-expressions to \refmodule{re} style regular expressions.  (For more
-conversion help, see Andrew Kuchling's\index{Kuchling, Andrew}
-``regex-to-re HOWTO'' at
-\url{http://www.python.org/doc/howto/regex-to-re/}.)
-
-
-\begin{funcdesc}{sub}{pat, repl, str}
-Replace the first occurrence of pattern \var{pat} in string
-\var{str} by replacement \var{repl}.  If the pattern isn't found,
-the string is returned unchanged.  The pattern may be a string or an
-already compiled pattern.  The replacement may contain references
-\samp{\e \var{digit}} to subpatterns and escaped backslashes.
-\end{funcdesc}
-
-\begin{funcdesc}{gsub}{pat, repl, str}
-Replace all (non-overlapping) occurrences of pattern \var{pat} in
-string \var{str} by replacement \var{repl}.  The same rules as for
-\code{sub()} apply.  Empty matches for the pattern are replaced only
-when not adjacent to a previous match, so e.g.
-\code{gsub('', '-', 'abc')} returns \code{'-a-b-c-'}.
-\end{funcdesc}
-
-\begin{funcdesc}{split}{str, pat\optional{, maxsplit}}
-Split the string \var{str} in fields separated by delimiters matching
-the pattern \var{pat}, and return a list containing the fields.  Only
-non-empty matches for the pattern are considered, so e.g.
-\code{split('a:b', ':*')} returns \code{['a', 'b']} and
-\code{split('abc', '')} returns \code{['abc']}.  The \var{maxsplit}
-defaults to 0. If it is nonzero, only \var{maxsplit} number of splits
-occur, and the remainder of the string is returned as the final
-element of the list.
-\end{funcdesc}
-
-\begin{funcdesc}{splitx}{str, pat\optional{, maxsplit}}
-Split the string \var{str} in fields separated by delimiters matching
-the pattern \var{pat}, and return a list containing the fields as well
-as the separators.  For example, \code{splitx('a:::b', ':*')} returns
-\code{['a', ':::', 'b']}.  Otherwise, this function behaves the same
-as \code{split}.
-\end{funcdesc}
-
-\begin{funcdesc}{capwords}{s\optional{, pat}}
-Capitalize words separated by optional pattern \var{pat}.  The default
-pattern uses any characters except letters, digits and underscores as
-word delimiters.  Capitalization is done by changing the first
-character of each word to upper case.
-\end{funcdesc}
-
-\begin{funcdesc}{clear_cache}{}
-The regsub module maintains a cache of compiled regular expressions,
-keyed on the regular expression string and the syntax of the regex
-module at the time the expression was compiled.  This function clears
-that cache.

Lib/lib-old/addpack.py

-# This module provides standard support for "packages".
-#
-# The idea is that large groups of related modules can be placed in
-# their own subdirectory, which can be added to the Python search path
-# in a relatively easy way.
-#
-# The current version takes a package name and searches the Python
-# search path for a directory by that name, and if found adds it to
-# the module search path (sys.path).  It maintains a list of packages
-# that have already been added so adding the same package many times
-# is OK.
-#
-# It is intended to be used in a fairly stylized manner: each module
-# that wants to use a particular package, say 'Foo', is supposed to
-# contain the following code:
-#
-#   from addpack import addpack
-#   addpack('Foo')
-#   <import modules from package Foo>
-#
-# Additional arguments, when present, provide additional places where
-# to look for the package before trying sys.path (these may be either
-# strings or lists/tuples of strings).  Also, if the package name is a
-# full pathname, first the last component is tried in the usual way,
-# then the full pathname is tried last.  If the package name is a
-# *relative* pathname (UNIX: contains a slash but doesn't start with
-# one), then nothing special is done.  The packages "/foo/bar/bletch"
-# and "bletch" are considered the same, but unrelated to "bar/bletch".
-#
-# If the algorithm finds more than one suitable subdirectory, all are
-# added to the search path -- this makes it possible to override part
-# of a package.  The same path will not be added more than once.
-#
-# If no directory is found, ImportError is raised.
