libraryaddict API
May be some useless stuff in here. Why not tho xD
API's:

receiveMsg(msg) - Just waits for rednet "msg"
event() - Pull event basically
eventRaw() -- Pull raw event basically.
send(id, msg) -- Rednet send/broadcast made little easier
layout(msg, style) -- Centers text and does your style down the side. so |    hi!   |
layoutOrder(mess, number, style) -- Centers text and does your style down the side. Also has the text not centered but at one thing
fillLine(style) -- Fills the line with stuff like "======="
center(y, mess) -- Centers text and prints it
slowCenter(y, mess, sec) -- Centers text and prints it slow
writeCenter(y, mess) -- Centers text and writes it
centerPrint(mess) -- Center print with no need to say y, Does it after text
centerWrite(mess) -- Center write with no need to say y, Does it after text
slowCenterPrint(mess, sec)-- Slow Center print with no need to say y, Does it after text
cursor(y) -- Set cursor up/down relative. use -1 or 1
removeline(filename, as many as you like lines.) -- Part of removePerm, This will remove certain lines from files
removelineNo(filename, unlimited line numbers) -- Part of removePerm, This will remove certain lines from files by the line number
insertLine(file, lineno, Insertline) -- insert lines into files
removePerm(Msg) -- removePerm(Msg) - Removes permant stored msgs from perm storage
compareMsgPerm(Msg)-- compareMsgPerm(Msg) - Check if it exists in perm storage
compareMsg(Msg)-- compareMsg(Msg) -- check if it exists in the temp storage
storePerm(Msg) -- storePerm(Msg) - Stores the msg permantly for use any time
store(Msg, Max) -- store(Msg, Max) - Stored in temp storage. Max is the max amount of msgs to store. default is 5
pulse(RPside, RPcount, RPperiod) -- Same as redpulse
printkeycode(times)  -- Prints whatever it hears
space(LinesToSkip) -- Calculates line and goes to the one after
copyOver(from, to) -- Copys over files from a place to a place
moveOver(from, to) -- Move file from A. to B.
Clear() -- Clears screen and sets cursor at 1,1
rsSet() -- Run before rsGet
rsGet() -- Run to return what rs input changed. Best to use after all rs events, currently works only for straight redstone. Not bundled.
checkDisk() -- Checks if disk exist and if it does return the diskside
writeVari(...) -- Writes variables to a file
clearLine() -- Clears line it was on and sets the cursor to 1, linenumber
writeFile(line, filename) -- Receives a string and writes it into a file. Best with sendFile
sendFile(filename, ID) -- Opens a file and sends it as a single string
tagView(msg) -- returns the msg as [RELAY] and so on. Strips [SOMETHING] away then returns it as a single thing. Also returns the msg destripped
tag(msg, tag) -- Add a tag
deTag(msg, tag) -- Remove specific tags
permVari(variname, contents) -- use to store a permanant variable to stay in usage. variable name, variable contents. make sure you use dofile in startup
removePermVari(variname) -- Remove from permanant load
checkTable(table, string) -- Check if string exists in the table
findFileName(table, string) -- Find the table with the string in it. So "hello" will find [hello there] but not [yo hello]
log(event) -- Logs the file. You use dofile to use it
bundle(Side, Color, True/False) -- Sets bundled output
centerBatch(Msg, MSg, msg, msg etc.) -- Do a bunch of text and it will center it
testBundle(side, color) -- Check if its on or off
openRednet() -- Opens rednet wireless. No need to define side.
monitor(side) -- Changes the screen to that side.
size(side, number) -- Changes text size on monitor
