# casm

Portable cross assembler.  Source control for this is now located in Subversion
at <a href="https://noddybox.co.uk/svn/casm/trunk">
https://noddybox.co.uk/svn/casm/trunk</a>.  The homepage is at
<a href="https://noddybox.co.uk/casm.php">
https://noddybox.co.uk/casm.php</a>.
Sorry, I tried to like GIT but 
found it's workflow not as comfortable as SVN for me.

## Usage

Simply pass it the file to assemble, i.e.

`casm source.txt`

Full documentation can be found in
<a href="https://rawgit.com/noddybox/casm/master/doc/casm.html">HTML</a> format.
