Usage: findlinks

Scans the current directory and any subdirectories, writing the names of
files which could be linked into the shared files repository to standard
output.  This list could be used as input to the \`mklinks' command.

### Read the names of all the files I support.

### Yes, this is ugly and hacky: well spotted.  Shells have a nasty habit of
### spontaneously forking when redirection gets too hard for them to think
### about, so instead of something nice along the lines of
###
###   find ... | while read name; do <build `files'> done
###
### I have to stick the whole lot in backticks and echo the result when it's
### all done.  Yuk.
###
### Oh, I almost forgot: that colon on the end there, that's to make sure
### that all the entries are surrounded by colons on both sides, which makes
### the pattern match in the `case' below work properly.

files=$(
  files=:
  find "$pkgdatadir" -type f -print | {
    while read name; do
      files="$files${name##*/}:"
    done
    echo "$files"
  }
)

###--------------------------------------------------------------------------
### Now examine the current directory.
###
### Remember to include things which are already linked, so that users can
### say `findlinks >.links' without any problems.

find . \( -type f -o -type l \) -print | while read name; do
