 This module reads and writes `/proc/[pid]/maps` files that contain listed mapped memory regions.
 
-# METHODS
+# FUNCTIONS
 
-## read\_maps %args
+## read\_maps
 
 Read and parse a maps file, returning an arrayref of regions (each represented as a hashref). See
 ["parse\_maps\_single\_line"](#parse_maps_single_line) to see the format of the hashrefs.
 
+    my $regions = read_maps(%args);
+
 Arguments:
 
 - `file` - Path to maps file
 - `pid` - Process ID (one of `file` or `pid` is required)
 - `mnt` - Absolute path where [proc(5)](http://man.he.net/man5/proc) is mounted (optional, default: `/proc`)
 
-## write\_maps \\@regions, %args
+## write\_maps
 
 Returns a string with the contents of a maps file from the memory regions passed.
 
+    my $file_content = write_maps(\@regions, %args);

 This is the opposite of ["read\_maps"](#read_maps).

 Parse and return a single line from a maps file into a region represented as a hashref.

 For example,

 # SEE ALSO
 
 [proc(5)](http://man.he.net/man5/proc) describes the file format.
 
+# CAVEATS
+
+Integer overloading may occur if you try to parse memory regions from address spaces larger than
+your current architecture (or perl) supports. This is currently not fatal, though you will get
+warnings from perl that you probably shouldn't ignore.
