Simple parse of text file to csv

OodaLoop has asked for the wisdom of the Perl Monks concerning the following question:

I for the life of me cannot find a useful example for my needs. I am looking for a simple example of parsing a text file and creating a CSV file. For example something that converts this text file:

Line1info
Line2someMoreInfo
Line3 more info

Line5line4IsBlank
    Line6isTabbed
    Line7isToo
Line8hasMoreStuff
[download]

into this CSV file:

Line1, Line3, Line6, Line7
Line1info, Line3 more info, Line6isTabbed, Line7isToo
[download]

I figured this would be a common request but apparently I was wrong. Every example I've found does not fit the bill. If someone could point me to an example that I could use as a template to learn from that would be great. If it is easy to produce an example from the generic data I provided that would be great too.

Just in case being more specific is helpful, here is exactly what I'm trying to do

Flat File

NetDevice1234
Kernel:
Linux 2.6.18-164.11
Version:
Driver 23.4.1 333.0
Hotfix BLD Edition

Hot fixes:
   HF372590
   HF372804
   HF372864
Enabled Features:
FTP 
HTTP
SMTP
Active Directory
[download]

Into a CVS with the following contents:

Host, OS, Version, Hot Fixes, Features
NetDevice1234, Linux 2.6.18-164.11, Driver 23.4.1 333.0 Hotfix BLD Edi
+tion, HF372590 HF372804 HF372864, FTP HTTP SMTP Active Directory
[download]

Thanks for any help you can provide everyone!
