Hi everyone,
I've got a problem with converting C comments ( /* */ ) into C++ style ( // ) in some source file with sed. So far I've dealt with comments on one line, but I don't know how to convert when it is over multiple lines ...
So I already have something like this:

PPI::Token::Comment(3) User Contributed Perl Documentation PPI::Token::Comment(3) NAME
PPI::Token::Comment - A comment in Perl source code INHERITANCE
PPI::Token::Comment isa PPI::Token isa PPI::Element SYNOPSIS
# This is a PPI::Token::Comment print "Hello World!"; # So it this $string =~ s/ foo # This, unfortunately, is not :( bar /w; DESCRIPTION
In PPI, comments are represented by "PPI::Token::Comment" objects. These come in two flavours, line comment and inline comments. A "line comment" is a comment that stands on its own line. These comments hold their own newline and whitespace (both leading and trailing) as part of the one "PPI::Token::Comment" object. An inline comment is a comment that appears after some code, and continues to the end of the line. This does not include whitespace, and the terminating newlines is considered a separate PPI::Token::Whitespace token. This is largely a convenience, simplifying a lot of normal code relating to the common things people do with comments. Most commonly, it means when you "prune" or "delete" a comment, a line comment disappears taking the entire line with it, and an inline comment is removed from the inside of the line, allowing the newline to drop back onto the end of the code, as you would expect. It also means you can move comments around in blocks much more easily. For now, this is a suitably handy way to do things. However, I do reserve the right to change my mind on this one if it gets dangerously anachronistic somewhere down the line. METHODS
Only very limited methods are available, beyond those provided by our parent PPI::Token and PPI::Element classes. line The "line" accessor returns true if the "PPI::Token::Comment" is a line comment, or false if it is an inline comment. SUPPORT
