 # This script should work correctly on any Linux or Unix-like operating

 # This script doesn't have any procs so everything is global, actually.

 # PARSE ALIASFILE: 
 # open ALIASFILE and parse each line. If the line matches a certain 
 # regular expression, the regex itself will pick the "key" and the "value", 
 # respectively. They're added to two Tcl lists: SIMKEYS and SIMVALUES. 
 # Finally, the number of aliases is counted.

 # PARSE SIMFILE:
 # open SIMFILE and parse each line. 
 # If line == [replace], this marks the beginning of the section we are going 
 # to "rewrite", or rather buffer in the NEWCONFIG global variable. So we 
 # buffer the "[replace]" mark (it is lost if not added explicitly) plus two 
 # required lines after that: LINE1 is whatever comes right after the 
 # "[replace]" mark. LINE2 is an indicator of the number of aliases the 
 # Replace plug-in should expect. Then we build the new list of keys and 
 # values and buffer that too. Finally, we flag up _ignore. That means we're 
 # parsing (and ignoring) old alias lines. If _ignore is flagged up, a regular 
 # expression tries to determine when the old alias section is over. When it 
 # is over, _ignore is flagged down again so the next iteration drops right 
 # to the last and most frequently used option (Option 3), which is adding the 
 # current line to NEWCONFIG.
