-        ##- in case of history a symbolic link is used because samtools (view) will generate
-        ##  the index which might not be possible in the directory containing the fasta file
-        ##- in case of cached the absolute path is used which allows to read the cram file

+        ## Make the user-selected reference genome, if any, accessible through
+        ## a shell variable $reffa, index the reference if necessary, and make
+        ## the fai-index file available through a shell variable $reffai.
+
+        ## For a cached genome simply sets the shell variables to point to the
+        ## genome file and its precalculated index.
+        ## For a genome from the user's history, if that genome is a plain
+        ## fasta file, the code creates a symlink in the pwd, creates the fai
+        ## index file next to it, then sets the shell variables to point to the
+        ## symlink and its index.
+        ## For a fasta.gz dataset from the user's history, it tries the same,
+        ## but this will only succeed if the file got compressed with bgzip.
+        ## For a regular gzipped file samtools faidx will fail, in which case
+        ## the code falls back to decompressing to plain fasta before
+        ## reattempting the indexing.
+        ## Indexing of a bgzipped file produces a regular fai index file *and*
+        ## a compressed gzi file. The former is identical to the fai index of
+        ## the uncompressed fasta.
+
+        ## If the user has not selected a reference (it's an optional parameter
+        ## in some samtools wrappers), a cheetah boolean use_ref is set to
+        ## False to encode that fact.
