 *Short Story*
 
 This is an unusual Galaxy tool capable of generating new Galaxy tools.
-It works by exposing *unrestricted* and therefore extremely dangerous scripting
-to all designated administrators of the host Galaxy server, allowing them to
-run scripts in R, python, sh and perl over multiple selected input data sets,
-writing a single new data set as output.
-
-*Differences between TF2 and the original Tool Factory*
-
-1. TF2 (this one) allows any number of either fixed or user-editable parameters to be defined
-for the new tool. If these are editable, the user can change them but otherwise, they are passed
-as fixed and invisible parameters for each execution. Obviously, there are substantial security
-implications with editable parameters, but these are always sanitized by Galaxy's inbuilt 
-parameter sanitization so you may need to "unsanitize" characters - eg translate all "__lt__" 
-into "<" for certain parameters where that is needed. Please practise safe toolshed.
-
-2. Any number of (the same datatype) of input files may be defined.
-
-These changes substantially complicate the way your supplied script is supplied with
-all the new and variable parameters. Examples in each scripting language are shown
-in the tool help

 *Automated outputs in named sections*
 
-If your script writes to the current directory path, arbitrary mix of (eg)
-pdfs, tabular analysis results and run logs,the tool factory can optionally
-auto-generate a linked Html page with separate sections showing a thumbnail
-grid for all pdfs and the log text, grouping all artifacts sharing a file
-name and log name prefix::

 ** Installation **
-This is a Galaxy tool. You can install it most conveniently using the
-administrative "Search and browse tool sheds" link. Find the Galaxy Main
-toolshed at https://toolshed.g2.bx.psu.edu/ and search for the toolfactory
-repository. Open it and review the code and select the option to install it.

-Of course, R, python, perl etc are needed on your path if you want to test
-scripts using those interpreters. Adding new ones to this tool code should
-be easy enough. Please make suggestions as bitbucket issues and code. The
-HTML file code automatically shrinks R's bloated pdfs, and depends on
-ghostscript. The thumbnails require imagemagick .

 * Restricted execution *
-The tool factory tool itself will then be usable ONLY by admin users -
-people with IDs in admin_users in universe_wsgi.ini **Yes, that's right. ONLY
-admin_users can run this tool** Think about it for a moment. If allowed to
-run any arbitrary script on your Galaxy server, the only thing that would
-impede a miscreant bent on destroying all your Galaxy data would probably
-be lack of appropriate technical skills.

+**Details and attribution** GTF_
+
+**Local Admins ONLY** Only users whose IDs found in the local admin_user configuration setting in universe_wsgi.ini can run this tool.
+
+**If you find a bug** please raise an issue at the bitbucket repository GTFI_
+
+**What it does** This tool enables a user to paste and submit an arbitrary R/python/perl script to Galaxy.
+
+**Input options** This version is limited to simple transformation or reporting requiring only a single input file selected from the history.
+
+**Output options** Optional script outputs include one single new history tabular file, or for scripts that create multiple outputs,
+a new HTML report linking all the files and images created by the script can be automatically generated.
+
+**Tool Generation option** Once the script is working with test data, this tool will optionally generate a new Galaxy tool in a gzip file
+ready to upload to your local toolshed for sharing and installation. Provide a small sample input when you run generate the tool because
+it will become the input for the generated functional test.
+
+.. class:: warningmark
+
+**Note to system administrators** This tool offers *NO* built in protection against malicious scripts. It should only be installed on private/personnal Galaxy instances.
+Admin_users will have the power to do anything they want as the Galaxy user if you install this tool.
+
+.. class:: warningmark
+
+**Use on public servers**  is STRONGLY discouraged for obvious reasons
+
+The tools generated by this tool will run just as securely as any other normal installed Galaxy tool but like any other new tools, should always be checked carefully before installation.
+We recommend that you follow the good code hygiene practices associated with safe toolshed.
+
+**Scripting conventions** The pasted script will be executed with the path to the (optional) input tabular data file path or NONE if you do not select one, and the path to the optional
+output file or None if none is wanted, as the first and second command line parameters. The script must deal appropriately with these - see Rscript examples below.
+Note that if an optional HTML output is selected, all the output files created by the script will be nicely presented as links, with pdf images linked as thumbnails in that output.
+This can be handy for complex scripts creating lots of output.
+
+**Examples**
+
+<![CDATA[
+Each of these following trivial examples can be cut and pasted into the script box for testing.
+Please make sure you choose the appropriate interpreter and upload and select a suitable small matching test data input
+
+A simple Rscript "filter" showing how the command line parameters can be handled, takes an input file, does something (transpose in this case) and 
+writes the results to a new tabular file. Note the use of colClasses to ensure that no fiddling takes place with numeric values by treating everything
+as a string::
+
+ # transpose a tabular input file and write as a tabular output file
+ ourargs = commandArgs(TRUE)
+ inf = ourargs[1]
+ outf = ourargs[2]
+ inp = read.table(inf,head=F,row.names=NULL,sep='\t',colClasses="character")
+ outp = t(inp)
+ write.table(outp,outf, quote=FALSE, sep="\t",row.names=F,col.names=F)
+
+Calculate a multiple test adjusted p value from a column of p values - for this script to be useful, it needs the right column for the input to be specified in the code for the
+given input file type(s) specified when the tool is generated ::
+
+ # use p.adjust - assumes a HEADER row and column 1 - please fix for any real use
+ column = 1 # adjust if necessary for some other kind of input
+ ourargs = commandArgs(TRUE)
+ inf = ourargs[1]
+ outf = ourargs[2]
+ inp = read.table(inf,head=T,row.names=NULL,sep='\t')
+ p = inp[,column]
+ q = p.adjust(p,method='BH')
+ outp = cbind(inp,'BH Adjusted p-value'=q)
+ write.table(outp,outf, quote=FALSE, sep="\t",row.names=F,col.names=T) 
+
+
+A demonstration Rscript example takes no input file but generates some random data based pdf images
+You must make sure the option to create an HTML output file is
+turned on for this to work. Images (pdf) are linked via thumbnails and
+all files have a link on the resulting HTML page::
+
+ # note this script takes NO input or output because it generates random data
+ for (i in 1:10) {
+    foo = runif(100)
+    bar = rnorm(100)
+    bar = foo + 0.05*bar
+    pdf(paste('yet',i,"anotherplot.pdf",sep='_'))
+    plot(foo,bar,main=paste("Foo by Bar plot #",i),col="maroon", pch=3,cex=0.6)
+    dev.off()
+    foo = data.frame(a=runif(100),b=runif(100),c=runif(100),d=runif(100),e=runif(100),f=runif(100))
+    bar = as.matrix(foo)
+    pdf(paste('yet',i,"anotherheatmap.pdf",sep='_'))
+    heatmap(bar,main='Random Heatmap')
+    dev.off()
+ }
+
+A slight variation taking an input tabular file from which we read the first number as nreps::
+
+ # note this script takes a single parameter
+ # number of replicates
+ ourargs = commandArgs(TRUE)
+ infname = ourargs[1]
+ nreps = read.table(infname,head=F)
+ nreps = unlist(nreps)[1]
+ nreps = max(c(1,nreps))
+ nreps = min(c(20,nreps))
+ print(paste("Using nreps=",nreps))
+ for (i in 1:nreps) {
+   foo = runif(100)
+   bar = rnorm(100)
+   bar = foo + 0.2*bar
+   pdf(paste("yet",i,"anotherplot.pdf",sep="_"))
+   plot(foo,bar,main=paste("Foo by Bar plot ",i),col="maroon", pch=3,cex=0.6)
+   dev.off()
+   foo = data.frame(a=runif(100),b=runif(100),c=runif(100),d=runif(100),e=runif(100),f=runif(100))
+   bar = as.matrix(foo)
+   pdf(paste("yet",i,"anotherheatmap.pdf",sep="_"))
+   heatmap(bar,main="Random Heatmap")
+   dev.off()
+ }
+
+A Python example that reverses each row of a tabular file (you'll need to remove the leading spaces 
+for this to work if cut and pasted into the script box)::
+
+ # reverse order of columns in a tabular file
+ import sys
+ inp = sys.argv[1]
+ outp = sys.argv[2]
+ i = open(inp,'r')
+ o = open(outp,'w')
+ for row in i:
+     rs = row.rstrip().split('\t')
+     rs.reverse()
+     o.write('\t'.join(rs))
+     o.write('\n')
+ i.close()
+ o.close()
+ 
+A trivial shell script example to show that it works::
+
+ #!/bin/bash
+ INF=$1
+ OUTF=$2
+ cut -c2,4,6,8,10,12 $INF > $OUTF 
+
+A trivial perl script example to show that even perl works::
+
+ #
+ # change all occurances of a string in a file to another string
+ #
+ $oldfile = $ARGV[0];
+ $newfile = $ARGV[1];
+ $old = "gene";
+ $new = "foo";
+ open(OF, $oldfile);
+ open(NF, ">$newfile");
+ # read in each line of the file
+ while ($line = <OF>) {
+    $line =~ s/$old/$new/;
+    print NF $line;
+ }
+ close(OF);
+ close(NF);
